ASoC: wm*: use simple i2c probe function
The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

wm8731.c is excluded and will be submitted separately.

This avoids scanning the identifier tables during probes.
