ASoC: Implement WM8994 OPCLK support
The WM8994 can output a clock derived from its internal SYSCLK, called OPCLK. The rate can be selected as a sysclk, with a division from the SYSCLK rate specified (multiplied by 10 since a division of 5.5 is supported) and the clock can be disabled by specifying a divisor of zero.
