Set of fixes to KVM's handling of the exception level event filtering in
the PMU event type registers.
I dropped the PMU+NV disablement this time around as we need a complete
fix for that problem. At the same time, I want to get a rework of our
sysreg masks upstream soon to avoid any negative interaction with new
PMU features going in on the driver side of things.
Additionally, I added a fix for the non-secure filtering bits that
Suzuki had spotted (thanks!)
