The ARMv8.3 PAuth (pointer authentication) extension adds:

- Fields in register ID_AA64ISAR1 to report the presence of pointer
authentication functionality.
- Control bits in SCTLR_ELx to enable this functionality.
- New registers to hold the keys necessary for this
functionality.
- New ESR_ELx.EC codes used when the new instructions are affected by
configurable traps

These will be used in later patches as support for pointer
authentication is added.

core: panic at unexpected smc return

Certain smc's are not expected to return. Prior to this patch in order
to guard against unexpected return a "b ." instruction was added after
each such smc to at least capture the cpu. With the introduction of FF-A
TF-A may in case there's a mismatch between OP-TEE and TF-A
configuration return some error code when an unrecognized smc is
encountered. The result is typically that the boot hangs after the print:
I/TC: Primary CPU switching to normal world boot

To help diagnosing such errors a call to panic is added after
each smc which isn't expected to return. The result becomes instead:
I/TC: Primary CPU switching to normal world boot
E/TC:0 Panic at core/arch/arm/kernel/boot.c:122 <__panic_at_smc_return>
