This patch adds support for implementing OMAP3 GPIO as an
early platform device and adds gpio_init specific to OMAP3

This patch adds device structures for each GPIO device in
OMAP3 architecture. These strutures are not created in a
separate *_data.c file because these structures would be
removed once the driver gets adapted to HWMOD way.
