ASoC: codecs: lpass-macro: Use enum for handling codec version

Replace 'int' with proper 'enum lpass_codec_version' in every place
which handles the parsed codec version (not raw register values!) to be
explicit about contents of the variable.  This makes code easier to read
and compilers could check missing switch cases.
