[PATCH -mmotm] gpio.h: fix warning for GENERIC_GPIO=n

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

Fix build for CONFIG_GENERIC_GPIO=n, which causes this warning:

include/linux/gpio.h:93: warning: 'struct device' declared inside parameter list
include/linux/gpio.h:93: warning: its scope is only this definition or declaration, which is probably not what you want
