Drivers: hv: Enable VTL mode for arm64
Kconfig dependencies for arm64 guests on Hyper-V require that be
ACPI enabled, and limit VTL mode to x86/x64. To enable VTL mode
on arm64 as well, update the dependencies. Since VTL mode requires
DeviceTree instead of ACPI, don’t require arm64 guests on Hyper-V
to have ACPI unconditionally.
