Apparently it is possible for firmware to indicate that SMCCC_VERSION is
implemented but have that call return NOT_SUPPORTED.  Makes no sense,
but the SMCCC standard documents this and tells us to treat this as v1.0.
Change the code accordingly.  Turn a few checks that should always be true
into KASSERTs to keep the control flow simple.
