Marc Zyngier 164b5e20cd KVM: arm64: nv: Handle CNTHCTL_EL2 specially 
Accessing CNTHCTL_EL2 is fraught with danger if running with
HCR_EL2.E2H=1: half of the bits are held in CNTKCTL_EL1, and
thus can be changed behind our back, while the rest lives
in the CNTHCTL_EL2 shadow copy that is memory-based.

Yes, this is a lot of fun!

Make sure that we merge the two on read access, while we can
write to CNTKCTL_EL1 in a more straightforward manner.
