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.
