[PATCH v2 2/6] drivers/hv: Enable VTL mode for arm64

[Roman Kisel]

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.
