[0/3] Fine grain sysregs allowed to trap for nested virtualization

Message

The current HCR_EL2 description includes _EL1 registers that are not affected
by NV. Let's exclude them from those ranges to implement a more fine grained
approach.

Miguel Luis (3):
  arm64: Add missing _EL12 encodings
  arm64/kvm: Fine grain _EL2 system registers list that affect nested
    virtualization
  KVM: arm64: nv: Handle all _EL02 and _EL12 registers
