ARM: bcm2835: enable GPIO/pinctrl

Browse source

Enable GPIO and pinctrl in Kconfig.

Add required <mach/gpio.h> for gpiolib.

Instantiate the BCM2835 GPIO module in bcm2835.dtsi.

Add a pinctrl definition to bcm2835-rpi-b.dts that sets up all of the
board's required pinmux configuration. GPIO aren't specified; that's
left to gpio_request().
