mfd: Add basic WM831x OTP support
The WM831x series of devices use OTP (One Time Programmable, a type of PROM) to store system configuration. At run time this data is visible via registers. Currently the only explicitly supported feature is that the unique ID provided by every WM831x device is exported to user space via sysfs. Other configuration data may be read by system-specific code in the pre_init() and post_init() platform data operations.
