This is based on mainline, without any extra ARMv9-A dependencies
which are still under development.  This is good enough to pass
all of the tests within

    https://github.com/Huawei/Huawei_CCA_QEMU

Changes for v3:
  * Incorporate fix for m-profile arm_cpu_get_phys_page_attrs_debug,
    since it has conflicts with the rest of the patch set.
  * Revert accidental change in S1_ptw_translate remapping
    ARMFault_GPCFOnOutput to ARMFault_GPCFOnWalk.
  * Remove __attribute__((nonnull)) early.
  * Rename get_phys_addr_{inner,outer} -> get_phys_addr_{nogpc,gpc}.

Changes for v2:
  * Drop "Fix pmsav8 stage2 secure parameter".
  * Incorporate review feedback.
  * Mark last two patches as "NOTFORMERGE".
