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.

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.
