Merge branch kvm-arm64/pkvm-selftest-6.16 into kvm-arm64/pkvm-np-thp-6.16

* kvm-arm64/pkvm-selftest-6.16:
  : .
  : pKVM selftests covering the memory ownership transitions by
  : Quentin Perret. From the initial cover letter:
  :
  : "We have recently found a bug [1] in the pKVM memory ownership
  : transitions by code inspection, but it could have been caught with a
  : test.
  :
  : Introduce a boot-time selftest exercising all the known pKVM memory
  : transitions and importantly checks the rejection of illegal transitions.
  :
  : The new test is hidden behind a new Kconfig option separate from
  : CONFIG_EL2_NVHE_DEBUG on purpose as that has side effects on the
  : transition checks ([1] doesn't reproduce with EL2 debug enabled).
