ACPI: make ACPI button funcs no-ops if not built in

Yakui pointed out that we don't properly no-op the ACPI button routines
if the button driver isn't built in.  This will cause problems if ACPI
is disabled, so provide stub functions in that case.

ACPI button: provide lid status functions

Some drivers need to know when a lid event occurs and get the current
status.  This can be useful for when a platform firmware clobbers some
hardware state at lid time, and a driver needs to restore things when
the lid is opened again.
