Initialize the number of accessible event counters

Set the number of event counters accessible from all exception levels
(MDCR_EL2.HPMN) to be the number of implemented event counters (PMCR_EL0.N).

This might have other security implications later.  Later work to investigate
how Hafnium should handle access to event counters.
