ASoC: max980*: use i2c_match_id and simple i2c probe 

As part of the ongoing i2c transition to the simple probe
("probe_new"), this patch uses i2c_match_id to retrieve the
driver_data for the probed device. The id parameter is thus no longer
necessary and the simple probe can be used instead.

In the context of an i2c probe, i2c_match_id with the module id table
and the probed client never returns null, so removing the null check
on the i2c_device_id pointer is safe.

The i2c id tables are moved up before the probe function, as
suggested by Wolfram Sang.
