ARM: 7083/1: rewrite U300 GPIO to use gpiolib
This rewrites the U300 GPIO so as to use gpiolib and
struct gpio_chip instead of just generic GPIO, hiding
all the platform specifics and passing in GPIO chip
variant as platform data at runtime instead of the
compiletime kludges.
As a result <mach/gpio.h> is now empty for U300 and
using just defaults.

The Intel Tunnel Creek processor has 5 GPIOs powered by the
core power rail and 9 from suspend power supply.

+ Say yes here to support GPIO interface on ST-Ericsson U300.
+ The names of the two IP block variants supported are
