Move all the gpio functions out of <mach/hardware.h> as this file is for defining the generic IO base addresses for the kernel IO calls. Make a new header <mach/gpio-fns.h> to take this and include it via the chain from <linux/gpio.h> which is what most of these files should be using (and will be changed as soon as possible). Note, this does make minor changes to some drivers but should not mess up any pending merges.
