ASoC: amd: update pm_runtime enable sequence

pm_runtime_allow() is not needed for ACP child platform devices.
Replace pm_runtime_allow() with pm_runtime_mark_last_busy()
& pm_runtime_set_active() in pm_runtime enable sequence for
ACP child platform drivers.

ASoC: amd: yc: acp6x-pdm-dma: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: amd: yc: Add a module parameter to influence pdm_gain

In case of regressions for any users that the new pdm_gain value is
too high and for additional debugging, introduce a module parameter
that would let them configure it.

This parameter should be removed in the future:
* If it's determined that the parameter is not needed, just hardcode
the correct value as before
* If users do end up using it to debug and report different values
we should introduce a config knob that can have policy set by ucm.

ASoC: amd: Migrate to new style legacy DAI naming flag

Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
These drivers appear to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

ASoC: amd: acp6x-pdm-dma: Constify static snd_soc_dai_ops

The only usage of acp6x_pdm_dai_ops is to assign its address to the ops
field in the snd_soc_dai_driver struct, which is a pointer to const
snd_soc_dai_ops. Make it const to allow the compiler to put it in
read-only memory.
