The mass erase for STM32L was lack because the procedure is more complex
than the procedure for the STM32F4xx.
The reference manual RM0038 (L100 subfamily) page 79 is more accurate
than the reference manual for the STM32L0xx. On the L0, the mass-erase
erase also the EEPROM. This is a limit to mass erase on L0.
The mass erase procedure is a command of telnet interface.
Tested on Discovery L053 and Discovery L100.

It's possible for us to fail to read the part ID code so make sure that
part_info is initialized to NULL before attempting to do so, otherwise
we could proceed and use it uninitialized and then segfault.

This adds initial support for the STM32L0 family, specifically the ID
code 417 variant. The 'L0 has 128B rather than 256B pages as well as a
different number of pages per sector. It also has several key registers
and register sets in different locations from the STM32L1xx parts.
This change therefore takes the opportunity to reorganize part information into
a const table (it was previously determined by a set of control statements) and
abstracts away some of the low-level details to make them generic for L1 and
L0 parts.
We also include the first bank's size (for dual bank parts) in the new
device information table (and correct that size for the 0x437 variant
which is 256 rather than 192KB).
The 'L0 parts will not use the built-in loader/helper for Flash writing.
Tested on STM32L053 (dicovery board and Nucleo board) and STM32L152
(discovery board).

This fixes an issue if the device is manually probed after the initial probe
fails due to being unable to read flash size register. In this situation the
driver assumes the user has overridden the flash size when infact this may
not be the case.
It also seems on the older stm32f1 devices the flash register is not readable
when locked, this does not seem to apply to the newer parts - f0, f3, f4.

This update adds support for the STM32Lx 384kb dual bank flash. Previously there was a problem when writing an
image that was larger than 192Kb. That lead to openocd printing out two error messages like
"Error: access denied / write protected" and "Error: invalid program address". The reason was that the stm32lx
driver tried to write half pages which overlapped into the next flash bank.
A new configuration file stm32lx_dual_bank.cfg can be used for stm32lx chips with dual bank flash (256kb or 384kb devices).
A sanity check was added for probed flash size values to fix the issue seen on some ST samples that answered incorrectly.

An issue has been seen with the stm32lx flash driver that if a

A similar issue is mentioned in the errata for the device.
Two solution's seem to workaround this issue:
1, Handle the exception, this means adding exception vectors to the loader
and changing the exception address using nvic vtor register.
2. falling back to using slower direct page writes - approx 50% slower.
Using solution 1 would mean restrictions are placed on the loader location.
Solution 2 was chosen mainly as it was simpler too implement.
