Define handlers specific to cAVS 1.5+ platforms, that is APL and similar platforms. These differ from SKL-alike ones in terms of AudioDSP firmware generation and thus the '+' suffix. Introduciton of IMR, removal of CLDMA, D0IX support and monolithic-ation of library/module code are most impactful but are not the only changes brought with this newer generation. Some generic and 1.5 operations are being re-used to reduce code size.
