Zelalem Aweke 8b95e84870 refactor(context mgmt): add cm_prepare_el3_exit_ns function 
As part of the RFC:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/13651,
this patch adds the 'cm_prepare_el3_exit_ns' function. The function is
a wrapper to 'cm_prepare_el3_exit' function for Non-secure state.

When EL2 sysregs context exists (CTX_INCLUDE_EL2_REGS is
enabled) EL1 and EL2 sysreg values are restored from the context
instead of directly updating the registers.

Bence Szépkúti 9d7251918d SiP: Don't validate entrypoint if state switch is impossible 
Switching execution states is only possible if EL3 is AArch64.
As such there is no need to validate the entrypoint on AArch32 builds.
