Merge branch kvm-arm64/psci-relay-fixes into kvmarm/next

* kvm-arm64/psci-relay-fixes:
  : Fixes for CPU on/resume with pKVM, courtesy Quentin Perret.
  :
  : A consequence of deprivileging the host is that pKVM relays PSCI calls
  : on behalf of the host. pKVM's CPU initialization failed to fully
  : initialize the CPU's EL2 state, which notably led to unexpected SVE
  : traps resulting in a hyp panic.
  :
  : The issue is addressed by reusing parts of __finalise_el2 to restore CPU
  : state in the PSCI relay.
  KVM: arm64: Finalise EL2 state from pKVM PSCI relay
  KVM: arm64: Use sanitized values in __check_override in nVHE
  KVM: arm64: Introduce finalise_el2_state macro
  KVM: arm64: Provide sanitized SYS_ID_AA64SMFR0_EL1 to nVHE
