flash/stm32l4x: STM32L55/L56xx basic support (non-secure mode)

Browse Source 
STM32L5 have 512 Kbytes of Flash memory with dual bank architecture.
STM32L5 flash is quite similar to L4 flash, mainly register names
and offsets and some bits are changed.
NON-SECURE flash is located at 0x8000000 like L4 devices, so no
big change is needed (secure flash will be subject of another change).

Note: flash driver name is set stm32l5x, in order to extend the commands
with specific L5 commands (to manage TZEN for example ...)

Note: this works only when TZEN=0

@deffn {Flash Driver} stm32l4x
All members of the STM32L4, STM32L4+, STM32WB, STM32WL and STM32G4
All members of the STM32 G0, G4, L4, L4+, L5, WB and WL
microcontroller families from STMicroelectronics include internal flash
and use ARM Cortex-M4 cores.
Additionally this driver supports STM32G0 family with ARM Cortex-M0+ core.
and use ARM Cortex-M0+, M4 and M33 cores.
The driver automatically recognizes a number of these chips using
the chip identification register, and autoconfigures itself.
