PATCH 1/1 Add pca9532 led driver

NXP pca9532 is a LED dimmer/controller attached to i2c bus. It allows attaching upto 16 leds which can either be on, off or dimmed and/or blinked with the two PWM modulators available.

This driver is a "new-style" i2c driver that adheres to the driver model and implements the led framework api. Since the leds connected to driver are platform specific, it is only usefull when platform data is passed to the driver to define what leds are connected to which pins.
