stm32l4x: add OTP support for STM32 G0/G4/L4/L4+/L5/WB/WL devices
this is a rework of #5320 started by Andreas then abandoned.
same syntax as in stm32f2x driver:
enable OTP for writing
> stm32l4x otp 1 enable
write to OTP
> flash write_bank 1 foo.bin 0
> flash filld 0x1FFF7000 0xDeadBeafBaadF00d 1
read OTP
> mdw 0x1FFF7000 4
disable OTP
> stm32l4x otp 1 disable
