MIPS: RB532: provide GPIO_BUILTIN_NR and irq_to_gpio/gpio_to_irq
This patchs defines the number of built-in the GPIOs present on the SoC as Documentation/gpio.txt recommends to do. Define irq_to_gpio/gpio_to_irq to return the right values so that it fixes a compilation error on drivers/gpio/gpiolib.c when enabling debugfs.
