FeaturePMU was created in AArch64 to accommodate one missing system
register, PMMIR_EL1, in commit ffcd7698aea7bcbb2b4edffc484793e1ff47b85d.

However, the Performance Monitors extension already had a target
feature, which is called FeaturePerfMon. Therefore, FeaturePMU is
redundant.

This patch removes FeaturePMU and merges its contents into
FeaturePerfMon.
