The 'flash list' command returns the driver name as flash name which seems
to be incorrect, the proposal is:
- to fix this by returning the flash name
- and add a new item 'driver' in the returned list
example:
before the change
> flash list
{name stm32l4x base 134217728 size 0 bus_width 0 chip_width 0}
{name stm32l4x base 201326592 size 0 bus_width 0 chip_width 0}
{name stm32l4x base 200933376 size 0 bus_width 0 chip_width 0}
after the change
> flash list
{name stm32l5x.flash_ns driver stm32l4x ...}
{name stm32l5x.flash_alias_s driver stm32l4x ...}
{name stm32l5x.otp driver stm32l4x ...}

STM32WB1x devices has a single flash bank up to 320 KB (page 2KB)
note: STM32WB5x/WB3x are single banks as well but do have 4KB as page size.
note: remove the assert that checks if max_mages is power of two, because
STM32WB1x flash size is not a power of 2

will reduce the maintenance effort.
besides the switch to C loader, we added a new parameters to the loader
like flash_word_size and flash_sr_bsy_mask in order to support properly
STM32U5x and STM32G0Bx/G0Cx in dual-bank mode.

this device flash registers are quite similar to STM32L5
with this changes :
- flash size is up to 2MB
- 2MB variants are always dual bank
- 1MB and 512KB variants could be dual bank (contiguous addressing)
depending on DUALBANK bit(21)
- flash data width is 16 bytes (quad-word)

according the RM0453, the second core have a different Flash CR and SR
registers for flash operations (called C2CR and C2SR).
so we need to a different flash_regs than older L4 devices.
@see stm32wl_cpu2_flash_regs
the C2CR register don't contain LOCK and OPTLOCK bits, and this explain
the addition of new register index called STM32_FLASH_CR_WLK_INDEX to
look-up the CR with lock, to be used in locking/unlocking the flash.
note: DBGMCU_IDCODE cannot be read using CPU1 (Cortex-M0+) at AP1,
to solve this read the UID64 (IEEE 64-bit unique device ID register)

When running OpenOCD with -fsanitize=undefined, a warning is emitted
for an bit-shifting operation whose result cannot be stored in a
signed integer.
This is because (1 << 31) overflows a signed integer, which is
undefined behavior. By making each of the bit masks act on an
unsigned number, the warning is avoided.
Whether this warning emitted by UBSan would ever manifest into a real
error is debatable, but fixing this does make UBSan happy.

This struct element is replaced by the usage of F_HAS_L5_FLASH_REGS flag:
since over this driver stm32l4_flash_regs is the default register layout,
and the only exception is STM32L5 family,
so it's simpler to manage it using a flag.
Note: the same flag will be used with STM32U5 devices, as they have
the same registers layout, which explains the move of stm32l5_s_flash_regs
before the switch(device_id) in order to not re-write this for STM32U5.
