arm/virt/acpi: remove _ADR from devices identified by _HID
According to ACPI spec, _ADR should be used for device on a bus that
has a standard enumeration algorithm, but not for device which is on
system bus and must be enumerated by OSPM. And it is not recommended
to contain both _HID and _ADR in a single device.
See ACPI 6.3, section 6.1, top of page 343:
A device object must contain either an _HID object or an _ADR object,
but should not contain both.
