[PATCH] add CONFIG_GENERIC_GPIO
Most drivers using GPIOs already know they are running on a system that supports the generic GPIO calls, because of other platform dependencies. But the generic GPIO-based LED and input button drivers can't know that. So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms where <asm/gpio.h> will do the right thing. Currently that's a bunch of ARMs, and AVR32; more are on the way. It also fixes a dependency bug for the gpio button input driver; it was wrong to start with, now it covers all platforms with GENERIC_GPIO.
