DA8xx: add generic GPIO driver
Add a generic GPIO driver for the DaVinci DA8xx processors. It is turned on by defining CONFIG_DA8XX_GPIO and fulfills the generic GPIO interface specified in <asm/gpio.h> . The driver has support for both manipulating GPIO pins as well as automatically configuring the pin multiplexor registers to set the pin function to GPIO.
