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 functions2009-09-10T23:09:11ZJesse Barnesjbarnes@virtuousgeek.org2009-09-10T22:28:02Zurn:sha1:7e12715ecc47a8a59154afe2746e48998225bb69
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.
