qcacmn: Control path support for Spectral DMA debug

Bläddra i källkod 
All gen III chipsets use Direct-DMA mechanism to copy Spectral reports to
the Host for further processing. This mechanism involves ring and buffer
management in the Host, FW, and uCode, where improper/incomplete DMA and
improper tail update issues are seen. DBR framework provides support to
debug such issues. Add Spectral control path support to facilitate the
configuration of these debug options.
