the DSP if the firmware supported compressed data capture. The buffer
struct (wm_adsp_compr_buf) is kept separate from the stream struct

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

This patch also adds a new naming scheme for controls created from rev 2
firmware files. This version of the file format is commonly used to
add multiple controls per algorithm per memory region and the old
