ASoC: codecs: lpass-macro: Gracefully handle unknown version

Qualcomm LPASS macro codec driver parses registers in order to
detect version of the codec.  It recognizes codecs v2.0 - v2.8, however
we know that there are earlier versions and 'enum lpass_codec_version'
has also v1.0, v1.1 and v1.2.  If by any chance we run on unrecognized
version, driver will use random value from the stack as the codec
version.

Fix it by mapping such cases to an enum of value 0:
LPASS_CODEC_VERSION_UNKNOWN.
