Subject: [PATCH] ASoC: Intel: sof_cs42l42: add support for adl_mx98360a_cs4242 and BT offload audio
This patch adds driver data for adl_mx98360a_cs4242 which supports
two max98360a speaker amplifiers on SSP1 and cs42l42 headphone codec
on SSP0 running on ADL platform. Also add the capability to machine
driver of creating DAI Link for BT offload. Although BT offload
always uses SSP2 port but we reserve the flexibility to assign
the port number in macro.
