flash/stm32l4x: STM32L5 support programming when TZEN=1 and RDP=0x55
when RDP level is 0.5 the provided work-area should reside in non-secure RAM
to ensure that:
- add a hint in the driver level
- reduce the usage of secure RAM only when TZEN=1 and RDP is not 0.5
(check the target configuration file)
