----------------------------------------------------------------
KVM/arm64 fixes for 6.19

- Ensure early return semantics are preserved for pKVM fault handlers

- Fix case where the kernel runs with the guest's PAN value when
  CONFIG_ARM64_PAN is not set

- Make stage-1 walks to set the access flag respect the access
  permission of the underlying stage-2, when enabled

- Propagate computed FGT values to the pKVM view of the vCPU at
  vcpu_load()

- Correctly program PXN and UXN privilege bits for hVHE's stage-1 page
  tables

- Check that the VM is actually using VGICv3 before accessing the GICv3
  CPU interface

- Delete some unused code
