Arunachalam Ganapathy 68ac5ed049 fix(el3_runtime): fix SVE and AMU extension enablement flags
If SVE are enabled for both Non-secure and Secure world along with AMU
extension, then it causes the TAM_BIT in CPTR_EL3 to be set upon exit
from bl31. This restricts access to the AMU register set in normal
world. This fix maintains consistency in both TAM_BIT and CPTR_EZ_BIT
by saving and restoring CPTR_EL3 register from EL3 context.
