firmware: cs_dsp: Remove unused struct list_head from cs_dsp_coeff_ctl
Remove two unused pointers from struct cs_dsp_coeff_ctl by taking the
struct list_head out of struct cs_dsp_alg_region. On a x86_64 build
this saves 16 bytes per control.
Each cs_dsp_coeff_ctl instance needs to keep information about the
algorithm region it refers to. This is done by embedding an instance
of struct cs_dsp_alg_region. But cs_dsp_alg_region was also used to
store entries in a list of algorithm regions, and so had a struct
list_head object for that purpose. This list_head object is not used
with the embedded object in struct cs_dsp_alg_region so was just
wasted bytes.
A new struct cs_dsp_alg_region_list_item has been defined for creating
the list of algorithm regions. It contains a struct cs_dsp_alg_region
and a struct list_head.
