ASoC: SOF: Intel: lnl/ptl: Only set dsp_ops which differs from MTL

LunarLake is a next generation in ACE architecture and most of the dsp_ops
are the same as it is in previous generation.
Use the sof_mtl_set_ops() to get the ops used for mtl and update the ones
that needs different functions for LNL.

Update pci-ptl at the same time to use the LNL dsp_ops as before.
