ARM: gpio: consolidate trivial gpiolib implementations

Consolidate 24 trivial gpiolib implementions out of mach/gpio.h
into asm/gpio.h.  This is basically the include of asm-generic/gpio.h
and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep
as described in Documentation/gpio.txt
