ok, so for this patch:

Acked-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

I accept the argument that when SSP2 is used for the amplifier then it
can't be used for BT offload, but I still find "mtl_mx98360_rt5682"
missing BT offload.  This would need a follow-up patch or a comment if
this miss was intentional (not formally supported).
