[PATCH 3/4] ASoC: intel: sof_cs42l42: add support for jsl_cs4242_mx98360a

This patch adds driver data for jsl_cs4242_mx98360a which supports two
max98360a speaker amplifiers on SSP1 and cs42l42 headphone codec on
SSP0 running on JSL platform. DAI format is leveraged from sof_rt5682
machine driver to reuse the topology.

Also use module device table to replace module alias.
