Notes:
- stm32l4_probe modified in order to charge the correct part_info from

- stm32l4_flash_bank.bank2_start is replaced by .part_info->bank1_sectors
- STM32_FLASH_BASE is removed , part_info->flash_regs_base will be used instead
based on that flash register addresses are changed to offsets,
>> stm32l4_get_flash_reg was modified accordingly
- stm32l4_read_option and stm32l4_write_option was modified to accept an

- stm32l4_mass_erase modifications :
- use MER2 only on top of dual bank devices
- wait for BUSY bit before starting the mass erase

STLINK-V3 and the new firmware V2J24 for ST-LINK/V2 provide API
to directly access the DAP registers.
This mode permits to use the native target in cortex_m.c, with no
need to override it with the target in hla_target.c.
Other advantages wrt HLA are: support for Cortex-A cores, support
for SoC multi-core and/or multi AP, support for OpenOCD commands
"dap" thus including control of CSW.
This obsoletes the existing HLA driver for ST-Link, that should
anyway be kept for those cases where it's not possible to update
the ST-Link firmware.
This commit introduces the minimal implementation for direct DAP
access. The implementation is much slower than the HLA because
every memory transfer requires several USB packets. Further
commits will close the performance gap.
The whole ST-Link driver is compiled under BUILD_HLADAPTER, to
remove the need to split the driver between the two modes. This
has to be reworked, but it's quite invasive!
A new interface file stlink-dap.cfg is added and should be used
in place of stlink.cfg to enable the DAP mode.
Documentation is updated and reports limitation on the maximum AP
number that can be accessed by ST-Link for some firmware already
tested.

After the cleanup of swd and hla, there should be no more calls

To prevent some remaining call to jtag_execute_queue() to crash

transport is not jtag, call the adapter's jtag_execute_queue()
only if it exist.
To identify code that still add commands in the jtag queue even
if transport is not jtag, print an error message in the function
jtag_queue_command(). For the moment, still queue the message,
even if will cause a memory leak if there is no following call
to jtag_execute_queue(); the target is to identify the issue and

The transport SWD uses the JTAG queue to assert/deassert the
system reset srst. This is the major inconsistency that has to be
removed to properly split JTAG and SWD.
Introduce a new driver API, reset(), to controls both the signals
trst and srst in the driver, skipping the JTAG queue. Put the new
API in struct jtag_interface, even if in this patch it's used for
SWD only; the goal is to get it reused by the other transports.
Add the implementation of the API in all the drivers that
implement SWD. Such implementation is almost the same of the old
code in JTAG queue.
Create a wrapper adapter_system_reset() to use the new API and
remove the SWD specific swd_add_reset(). In the wrapper replace
jtag_add_sleep() with jtag_sleep(), because the former uses the
JTAG queue too.
Rename the old jtag_add_reset() as legacy_jtag_add_reset() with
the target to remove it when all drivers would be ported to the
new reset API. Create a new jtag_add_reset() that calls the
legacy function for drivers still on the old reset API.
Use the new API also on JTAG transport for the drivers that can
support both SWD and JTAG.
For the moment, do not modify the implementation of JTAG-only
drivers, which will continue using the usual method. This should
be cleaned-up in future commits.

* Handle DMI busy in sba write.
If we encounter DMI busy on the NOP after a read, we'll never get the
value out because DMI busy is sticky. The read must be retried, but we
don't know whether it was ever issued. Since the read has side effects
(incrementing of the address) this retry must be handled at a higher
layer. So now dmi_op_timeout can be told to retry or not, and if retry
is disabled it'll return an error when busy.
Also actually properly do the retry in dmi_op_timeout(). Previously the
code would not reissue the command and end up returning a garbage value.

The current code assumes an STM32's flash bank is laid-out in either of
two configurations:
- 4 x 16kB + 1 x 64kB + n x 128kB
- 4 x 32kB + 1 x 128kB + n x 256kB
This is quite ad-hoc but works fine in practice, as long as there are at
least 5 sectors (if n=0). Unfortunately, some newer STM32s are shipping
with only 64 kB of flash (4 x 16kB sectors).
This patch still assumes the same sector layout, but only keeps adding
sectors to the bank if the bank's capacity has not been reached. This
prevents openocd from crashing on some newer STM32s.

* riscv: Fix bugs. Do not touch SATP if there is no MMU.
In some platform, there is no SATP register at all.
OpenOCD will report unexpected errors if SATP is unreadable.
So, use 'riscv_enable_virtual' to guard SATP access.
* riscv: fix format typo.
The SWO frequency auto-detection with J-Link adapters does not work
properly in the current implementation. This is because the trace layer
has only information about the highest possible SWO frequency supported
by the adapter. With that the trace layer calculates the SWO prescaler
which usually leads to a frequency deviation greater than what is
permitted by J-Link adapters.
Move the calculation of the SWO prescaler from the trace layer into the
trace configuration of the adapter to overcome this problem.
The adapter has the necessary information to choose a suitable SWO
frequency and calculate the corresponding prescaler that complies with
the maximum allowed frequency deviation.
Tested with:
- STM32L152RC Discovery Kit (ST-Link)
- EFM32GG-STK3700 (J-Link)
