acpi: x86: remove _ADR on host bridges
ACPI spec (since 2.0a) says
"
A device object must contain either an _HID object or
an _ADR object, but can contain both.
"
_ADR is used when device is attached to an ennumerable bus,
however hostbridge is not and uses dedicated _HID for
discovery, drop _ADR field.
It doesn't seem that having _ADR has a negative effects
OSes manage to tolerate that, but there is no point of
having it there. (only pc/q35 has it hostbridge description,
while others (microvm/arm) don't)
