Currently, the FEAT_EBEP feature presence check is only used for UNDEF
injection into lower ELs. However, this feature also affects the access
behavior of MDCR_EL2. Specifically, if the PMEE bits in MDCR_EL3 are not
set to 0b01, then the MDCR_EL2.PMEE bits cannot be configured by EL2.
This patch extends the use of FEAT_EBEP to delegate PMU IRQ and
profiling exception control to EL2 by setting MDCR_EL3.PMEE = 0b01.This
ensures that lower ELs can manage PMU configuration.
