refactor(stm32mp1): update backup reg for FWU

Change the backup register used to store FWU parameters from 21 to 10.
This is chosen to have a Read/Write secure and Read non-secure register.
The mapping is also changed: only the first 4 bits will be used to store
the FWU index. The 4 next bits will be used to store count info. The
other bits are reserved.
