KVM on ARM relies on device tree information, which is not available
when booting with ACPI. In the case of VGIC we need to extract
the relevant data from the MADT table and probe it accordingly.
For the architected timer, we need to expose the correct
interrupt line to KVM from the GTDT table.
This series has been tested on the Foundation Model 0.8 build 5206
and is based on the "Introduce ACPI for ARM64 based on ACPI 5.1"
patch series from Hanjun Guo.

ARM64 / ACPI: Point KVM to the virtual timer interrupt when booting
with ACPI
