leds: Add WM831x status LED driver
The WM831x devices feature two software controlled status LEDs with hardware assisted blinking. The device can also autonomously control the LEDs based on a selection of sources. This can be configured at boot time using either platform data or the chip OTP. A sysfs file in the style of that for triggers allowing the control source to be configured at run time. Triggers can't be used here since they can't depend on the implementation details of a specific LED type.
