leds: Add pca9532 platform data for Thecus N2100 

Thecus N2100 has leds and a buzzer attached to a pca9532 controller.  Attach
the driver to the i2c bus and define the pca9532 pin coniguration for this
platform in n2100_leds.

With this patch, support for N2100 should be complete in mainline Linux.
