arm64/sysreg: Use feature numbering for PMU and SPE revisions
Currently the kernel refers to the versions of the PMU and SPE features by
the version of the architecture where those features were updated but the
ARM refers to them using the FEAT_ names for the features. To improve
consistency and help with updating for newer features and since v9 will
make our current naming scheme a bit more confusing update the macros
identfying features to use the FEAT_ based scheme.
