Following system registers are modified before exiting EL2 to allow
u-boot/Linux to boot
1. CNTHCTL_EL2.EL1PCTEN -> 1
Allows U-boot to use physical counters at EL1
2. VTCR_EL2.MSA -> 1
Enables VMSA at EL1, which is required by U-Boot and Linux.
3. HCR_EL2.APK = 1 & HCR_EL2.API = 1
Disables PAuth instruction and register traps in EL1
