ASoC: wm_adsp: Move DSP Rate controls into the codec

The rate controls are codec-specific, it's not possible to
generically say what the range or the meaning of each control
is (or even if they exist at all) - that depends on the
particular codec.

This is currently being handled for Arizona codecs by putting
an Arizona-specific table of controls inside the wm_adsp driver.
This creates a dependency between wm_adsp and arizona.c, and is an
awkward solution if the ADSP is used in another family of codecs

Fix this by moving the Arizona-specific rate controls into the
Arizona codec drivers.
