MIPS: RB532: GPIO register offsets are relative to GPIOBASE
This patch fixes the wrong use of GPIO register offsets
in devices.c. To avoid further problems, use gpio_get_value
to return the NAND status instead of our own expanded code.
Also define the zero offset of the alternate function register to allow
consistent access.
