ASoC: fsl-asoc-card: Move bound-component setup to late_probe

Browse source

Move all operations that require bound codec and CPU DAI components out
of probe() and into late_probe(), which is the correct place for them
now that ASoC supports deferrable card binding. late_probe() may be
called multiple times after an unbind/rebind cycle, so every
initialization step is guarded accordingly.

Three new helpers are introduced:
- fsl_asoc_card_init_cpu()
  CPU DAI-specific setup. Previously done in probe() while CPU DAI
  component maybe not ready.

- fsl_asoc_card_init_codecs()
  Reads codec MCLK rates from the bound component devices, invokes the
  per-compatible pdata->codec_init callback if present.

- fsl_asoc_card_init_jack()
  Registers headphone and microphone jacks.

The call site of codec_init callbacks moves from probe() to
fsl_asoc_card_init_codecs(), which runs in late_probe() after the bound
codec device is known. This makes sure codecs can get proper MCLK.

The old card-name fallback depended on codec_dev_name[], which required
looking up the codec device in probe(). This is no longer valid under
deferrable card binding because the codec component may not have probed
yet. Since the DT binding requires "model", remove the fallback and fail
with a clear error.
