From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 7c936d8d26afbc74deac0651d613dead2f76e81c ]

Cleanup the ACER_CAP_FOO defines:
-Switch to using BIT() macro.
-The ACER_CAP_RFBTN flag is set, but it is never checked anywhere, drop it.
-Drop the unused ACER_CAP_ANY define.
