If the platform set the dyn_pcm_assign to true, it will call

So far only intel_hsw_common_init() and patch_nvhdmi() set the
dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot
dynamically first, if the driver runs for a period of time and there
is no regression reported, we could set no_fixed_assgin to true in
the intel_hsw_common_init(), and then set it to true in the
patch_nvhdmi().
This change comes from the discussion between Takashi and
Kai Vehmanen. Please refer to:

As this would "fix" actual use cases, I'd love to merge this for 5.12,
but of course it needs to be verified beforehand.
So this was actually tested in your side, right?
I tested it on TGL machines with Ubuntu, both sof and legacy hda, so
far there is no regression.

Hui.
thanks,
