firmware: xilinx: enable feature check for ZynqMP 

Enable the feature check if the PM_FEATURE_CHECK API returns success
with the supported version for the ZynqMP. Currently, it is enabled
for Versal only.

Move get_set_conduit_method() at the beginning as the Linux is
requesting to TF-A for the PM_FEATURE_CHECK API version for which the
interface should be enabled with TF-A.
