flash/stm32l4x: STM32L5 support programming when TZEN=1 and RDP=0xAA

Browse Source 
STM32L5 flash memory is aliased to 0x0C000000, this address mapping
is used for secure applications. (0x08000000 for non-secure)

this change allows the programming of secure and non-secure flash
when trustzone is enabled and RDP level is 0
