dev/psci: Check for functions before calling
In the SMCCC TRNG and Errata ABI drivers check if the version
functions are implemented before calling them. Without this the firmware
may complain about an unimplemented function being called.

I wonder if a debug mode or verbose mode should report
the != SMCCC_RET_SUCCESS cases for smccc_arch_features.
If this change had already been in place, the older
status might not have been noticed. As bz wrote
elsewhere:
"That said seems like it's still a good idea to add
these bits to my TF-A."
Having a way to check on if a TF-A instance is too
old to have a known status for handling things that
are now requested could be a good thing.
Please read the comments on the review.
