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