ASoC: codecs: wcd939x: Use simple defines for chipid register value

The value used to identify chip variant is not an enumeration, but raw
value used to compare registers with.  The 'enum' is not used in the
code at all, so simplify and make it a raw hex value define, so
intention will be explicit.
