[PATCH v3 0/2] KVM Support for imx8mp-evk Machine

[Bernhard Beschow <shentey@gmail.com>]

This series adds KVM support to the imx8mp-evk machine, allowing it to run
guests with KVM acceleration. Inspiration was taken from the virt machine. This
required a device tree quirk for the guest clock to be kept in sync with the
host. Without this quirk the guest's clock would advance with factor <host
system counter> / 8Mhz.

Testing done:
* Run `make check`
* Run Buildroot image with TCG
* Run `qemu-system-aarch64 -M imx8mp-evk -accel kvm -smp 4` under
  `qemu-system-aarch64 -M virt,secure=on,virtualization=on,gic-version=4 \
  -cpu cortex-a72 -smp 4 -accel tcg` and `qemu-system-aarch64 -M imx8mp-evk \
  -accel tcg -smp 4". Observe that the `date` command reflects the host's date.

v3:
* Fix crash in qtest (Peter) by using cortex-a53 CPU when ms->cpu_type == NULL
* Apply Peter's style fixes in board documentation
* Apply Phil's R-b -- thanks!
* Rebase onto master

v2:
* Rebase onto master
* Mention various tradeoffs in the board documentation (Peter)
* Accommodate for single-binary (Peter, Pierrick) by having CPU defaults
* Add quirk to fix guest clock
