ASoC: SOF: Intel: split MTL and LNL operations

It was just a matter of time before we found a case where we needed
separate ops for MTL and LNL. For LNL we need to set the DMIC/SSP
OFLEN bit in the probe and resume steps, and this can only be done
cleanly with separate ops.

The function prototypes in mtl.h were added in the same order as their
implementation in mtl.c.
