[PATCH v4 0/3] ASoC: add Senary SN624x SoundWire SDCA support

[Qianghua Wang <qianghua.wang@senarytech.com>]

This series adds SoundWire SDCA support for Senary SN624x
multi-function codecs (jack, speaker amp, DMIC) on Intel ARL,
LNL, MTL, and PTL.

v3 was dropped due to a CI build break against current SDCA
helpers, so this is a full resend with those fixes folded in
(not an incremental on top of v3).

Changes since v3:
- Enable runtime PM from io_init() on first ATTACHED, matching
  the rt722 pattern, instead of enabling it from probe after
  register_component().
- Update sdca_asoc_pde_poll_actual_ps() / sdca_parse_function()
  call sites to the current prototypes (drop unused device and
  SoundWire slave arguments) so the driver builds on for-next.

Changes since v2:
- Propagate io_init Function Status / defaults failures instead of
  skipping init and still returning success.
- Zero-initialize sdw stream/port configs and use
  snd_sdw_params_to_config().
- Program jack SampleFreqIndex only for the configured stream
  direction (avoid forcing symmetric rates).
- Mark regmap cache dirty on suspend and on re-io_init after
  re-attach so regcache_sync restores state after power loss/reset.
- Hold a long-lived runtime PM get while jack detect is enabled
  via set_jack / remove (drop poll mark_last_busy refresh).
- Use sdw_slave_wait_for_init() on resume when unattach_request
  is set.

Patch summary:
  1/3  codec driver + MAINTAINERS
  2/3  sdw_utils helpers and codec_info
  3/3  Intel ARL/LNL/MTL/PTL ACPI match + SOF mach select

Validated on LG Wildcat Lake / PTL with part_id 0x6247
(MODALIAS sdw:m0496p6247v03c01).
