Enable write traps for key EL3 system registers as per FEAT_FGWTE3,
ensuring their values remain unchanged after boot.
Excluded Registers:
MDCR_EL3 and MPAM3_EL3: Not trapped as they are part of the EL3 context.
SCTLR_EL3: Not trapped since it is overwritten during
powerdown sequence(Included when HW_ASSISTED_COHERENCY=1)
TPIDR_EL3: Excluded due to its use in crash reporting(It is included
when CRASH_REPORTING=0)
