of get_vtl() so that it can be used on arm64.

This set of patches enables the Hyper-V code to boot on ARM64
inside a Virtual Trust Level. These levels are a part of the
Virtual Secure Mode documented in the Top-Level Functional
Specification available at
https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/tl
From: Roman Kisel
This change builds upon the previous ones to boot
in a Virtual Trust Level and provide configuration
for the drivers.
Also print the VTL the code runs in the new and the
existing code.

This change removes dependency on ACPI when buidling the hv drivers to
allow Virtual Trust Level boot with DeviceTree.

When booting on arm64, one has to configure the irq
using the data from the system configuration. There
has already been support for ACPI, support DeviceTree
as booting in a Virtual Trust Level relies on DT.

Update the driver to support DeviceTree boot as well along with ACPI.
This enables the Virtual Trust Level platforms boot up on ARM64.
