topology: Define a function to build a single PCM element

Browse source 
Code refactoring. Rename tplg_build_pcm() to tplg_build_pcms() to build
all PCM (FE DAI & DAI link) elements. It will call a new function
build_pcm() to build a single PCM elemement.

build_pcm() will be extended to handle more properties of a PCM.
