Hmm.  It shouldn't have been deleted - Linus' patch leaves the file
empty rather than deleting it.

However, as I had to use GNU patch to apply Linus' patch (as git apply
wouldn't because of fuzz), it doesn't understand that, so it removed it.
This is where having an /* empty */ comment avoids that kind of thing,
just like I've done for all the other mach/gpio.h which became empty.
