hv: shadow perf monitor IRQ mode and state
...
The development Mac OS kernel panics if the PMCR0 sysreg is in an
unexpected state. To avoid that the hypervisor needs to shadow the
interrupt mode and interrupt active flag after it mask the PM FIQ.
Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling
in m1n1 is preferred over Python.
