This patch adds very basic device tree binding support to the
pca9532 driver. Sufficent to load driver and enable LEDs.

Changes for v5:
- Address warning on 64bit builds. Change devid cast to unitptr_t.
- Make pca9532_of_populate_pdata static.

Changes for v4:
- Reference leds/common.txt in documentation.
- Check return value of of_match_device()

Changes for v3:
- Remove state from device tree binding.
  This needs more thought on how to configure which PWM is used.
  And is not essential for a first pass.

Changes for v2:
- Fixup device tree documentation
- Use label propert and fall back to node name,
- Call of_node_put when breaking loop iterating leds.
- Increment the loop counter.
- Add initial state and default-trigger.
