Allow unused leds on pca9532 to be used as gpio. The board I am working
on now has no less than 6 pca9532 chips. One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.
There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
232 { .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
233 { .type = PCA9532_TYPE_NONE }, /* reset gpio */
This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set. The gpio will registers all chip
pins but will filter on gpio_request.
