This patch moves generic common code to src.c/h from src_core.c/h and places generic C optimized filter to src_generic.c. The HiFi EP version is in src_hifi2ep.c and HiFi3 version is in src_hifi3.c. Use of the Xtensa optimized versions require xt-xcc compiler.
The non-used SRC in/out rates query code is removed. The 24 bit coefficients were replaced by 32 bit coefficients those are compatible with Xtensa fractional integer types.
