("[PATCH for-8.0 v4 0/4] target/arm: pre-FEAT_RME fixes")

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 v4:
  * Rebase, all except the NOTFORMERGE patches are reviewed.
