This is the third version of the series initially posted at [1],
which

- updates the ACPI GTDT parsing to deal the v3 layout and the EL2
virtual timer,
- moves the architected timer driver to use it when running VHE,
- fixes a number of DTs to reflect the reality of the HW.

This results in significant performance uplift in deeper nested virt
scenarios, at no overhead to the host.

Patches based on -rc3, tested on Amlogic SM1, QC X1E, Ampere Altra,
and Apple M2, as well as KVM NV guests.

Daniel, can you please pick the first 3 patches? Or would you rather
have them routed via the arm64 tree?

I'll pick them up

Thanks
