arm64: errata: use arm_smccc_1_1_get_conduit()

Browse source

Now that we have arm_smccc_1_1_get_conduit(), we can hide the PSCI
implementation details from the arm64 cpu errata code, so let's do so.

As arm_smccc_1_1_get_conduit() implicitly checks that the SMCCC version
is at least SMCCC_VERSION_1_1, we no longer need to check this
explicitly where switch statements have a default case, e.g. in
has_ssbd_mitigation().

There should be no functional change as a result of this patch.
