ipq806x: implement GPIO API
Add implementation of the GPIO API defined in src/include/gpiolib.h.
Also, clean up the GPIO driver, make it use pointers instead of
integers for register address.
This requires a touch in the SPI driver, where the CS GPIO is toggled
and in the board function where it enables USB interface.
BUG=chrome-os-partner:30489
TEST=tested with the following patches, observed proto0 properly read
the board ID.
