The avs-driver continues to be utilized on more recent Intel machines. As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality from previous platforms: SKL <- APL <- CNL <- ICL <- TGL rather than putting everything into a single file, the platform-specific bits are split into cnl/icl/tgl.c files instead. Makes the division clear and code easier to maintain. Layout of the patchset: First are two changes combined together address the sound-clipping problem, present when only one stream is running - specifically one CAPTURE stream. Follow up is naming-scheme adjustment for some of the existing functions what improves code incohesiveness. As existing IPC/IRQ code operates solely on cAVS 1.5 architecture, it needs no abstraction. The situation changes when newer platforms come into the picture. Thus the next two patches abstract the existing IPC/IRQ handlers so that majority of the common code can be re-used. The ICCMAX change stands out a bit - the AudioDSP firmware loading procedure differs on ICL-based platforms (and onwards) and having a separate commit makes the situation clear to the developers who are going to support the solution from LTS perspective. For that reason I decided not to merge it into the commit introducing the icl.c file.
