Nack.

There's an ordering problem.  The #inclusion of asm-generic/gpio.h must come
both before *and* after the functions in asm/gpio.h.  Take gpio_get_value()
for instance, it requires __gpio_get_value() - which is defined by the generic
header - but is used by gpio_get_value_cansleep() in the generic header.

You must split asm-generic/gpio.h.
