Subject: [PATCH] ASoC: mediatek: mt8195: Remove afe-dai component and rework codec link
Remove the extra 'mt8195-afe-pcm-dai' component, register the DAI
drivers to the main AFE component, and rework the DAI linking between
the headset codec (RT5682/RT5682S) and the TDM interface in the probe
function to stop assigning name, relying on the of_node of the codec.
Also replace the COMP_DUMMY codec entry with a COMP_EMPTY for the
ETDM2_IN and remove it entirely from ETDM1_OUT to fix the registration
flow for this sound card.
While at it, since we also need to swap the codec init function from
ETDM2_IN to ETDM1_OUT, remove the static assignment of both `ops` and
`init` for both, as we now assign these dynamically during probe.
Fixes: 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()")

This was tested on the MT8195 Cherry Tomato Chromebook w/Pipewire:
audio works again with both internal speakers and 3.5mm jack.
As a (mostly personal) note, this driver's probe function should get
refactored at some point to rely on snd_soc_of_parse_audio_routing()
instead; I plan to do that as soon as I can (bandwidth permitting...!)
