KVM/arm64 updates for 6.18

- Add support for FF-A 1.2 as the secure memory conduit for pKVM,
  allowing more registers to be used as part of the message payload.

- Change the way pKVM allocates its VM handles, making sure that the
  privileged hypervisor is never tricked into using uninitialised
  data.

- Speed up MMIO range registration by avoiding unnecessary RCU
  synchronisation, which results in VMs starting much quicker.

- Add the dump of the instruction stream when panic-ing in the EL2
  payload, just like the rest of the kernel has always done. This will
  hopefully help debugging non-VHE setups.

- Add 52bit PA support to the stage-1 page-table walker, and make use
  of it to populate the fault level reported to the guest on failing
  to translate a stage-1 walk.

- Add NV support to the GICv3-on-GICv5 emulation code, ensuring
  feature parity for guests, irrespective of the host platform.

- Fix some really ugly architecture problems when dealing with debug
  in a nested VM. This has some bad performance impacts, but is at
  least correct.

- Add enough infrastructure to be able to disable EL2 features and
  give effective values to the EL2 control registers. This then allows
  a bunch of features to be turned off, which helps cross-host
  migration.

- Large rework of the selftest infrastructure to allow most tests to
  transparently run at EL2. This is the first step towards enabling
  NV testing.

- Various fixes and improvements all over the map, including one BE
  fix, just in time for the removal of the feature.
