register_cache_invalidate() is written a way which uses
pointer arithmetic, which makes it harder to read. This patch
replaces it with more readable way to iterate over array of

Lot of messages was logged as LOG_WARNING, but the operation failed
immediately. Sometimes no error message was logged at all.
Add missing messages, change warnings to errors.
Sometimes ERROR_TARGET_INVALID was returned. Some command handlers
returned ERROR_OK! Always return ERROR_TARGET_NOT_HALTED.
While on it use LOG_TARGET_ERROR() whenever possible.
Prefix command_print() message with 'Error:' to get closer
to LOG_TARGET_ERROR() variant.
Error message was not added to get() and set() methods of
struct xxx_reg_type - the return value is properly checked and a message
is logged by the caller in case of ERROR_TARGET_NOT_HALTED.

While not affecting the function's main purpose, an error has
crept into arc_save_context() that results in logging wrong register

printed to the log:

This patch adds support for the NXP QN908x family of Bluetooth
microcontrollers, such as the QN9080. This chip features a Cortex-M4F
with 512 KiB of flash on all the available versions, although the
documentation suggests that there might be 256 kB versions as well.
The initial support allows to read, erase and write the whole user flash
area. Three new sub-commands under the new "qn908x" command are added
in this patch as well: disable_wdog to disabled the watchdog,
mass_erase to perform a mass erase and allow_brick to allow programming
images that disable the SWD interface.
Disabling the watchdog is required after a "reset halt" in order to run
the CRC algorithm from RAM when verifying the chip. However, this is not
done automatically on probing or other initialization since disabling
the watchdog might interfere with debugging real applications.
The "mass_erase" command allows to erase the whole flash without
probing it, since in some scenarios the chip can be locked such that no
flash or ram can be accessed from the SWD interface, allowing only to
run a mass_erase to be able to flash the program.
The flashing process allows to compute a checksum, similar to the
lpc2000 driver "calc_checksum" but done over a different region of the
memory. This checksum is required to be present for the QN908x
bootloader ROM to boot, and otherwise is useless. As with the lpc2000
design, verification when using "calc_checksum" is expected to fail if
the checksum was not valid in the image being verified.
This was manually tested on a QN9080, including the scan-view,
AddressSanitizer/UBSan and test coverage configurations.

- an empty bss segment with paddr in FLASH causes excessive flash

The bcm2835gpio driver preferred /dev/gpiomem for access to
memory mapped GPIO control and used /dev/mem as a fallback
only if it couldn't open /dev/gpiomem.
/dev/mem usually requires elevated rights or specific capabilities
of the opening process, so the fallback failed anyway.
Although /dev/gpiomem is the strongly preferred option with respect
to security, there could be also use cases which require /dev/mem
even if /dev/gpiomem is available (e.g. changing the GPIO pad
settings is necessary or testing/debugging OpenOCD).
It was difficult to handle such cases because they required
to block globally the system device /dev/gpiomem
(remove, rename or chmod).
Drop the fallback feature and select the memory device
by 'bcm2835gpio peripheral_mem_dev' configuration command.
Use /dev/gpiomem as a default.
