Mark Brown 973838a030 ASoC: wm_adsp: Enable DVFS for ADSP2 
Some ADSP devices can make use of DVFS to optimise power consumption
depending on the operating frequency of the DSP core. Implement
support for this in the generic ADSP code.

Mark Brown 2159ad936b ASoC: adsp: Add ADSP base support 
Many current Wolfson devices feature DSPs based around an architecture
known as ADSP.  Since there is a lot of commonality in the system
integration of these devices a common library will be used to provide
support for them.

This version provides equivalent support for ADSP1 to that currently
included in the WM2200 driver.
