[PATCH v4 00/16] ASoC: amd: acp: ACP7.B/7.F SoundWire machine driver support

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

This series adds SoundWire machine driver support for ACP7.B and ACP7.F
platforms. It extends the existing AMD ACP SoundWire infrastructure with
per-platform CPU pin ID lookup, PDM controller selection via ACPI and DMI
quirks, DMIC DAI link and components string handling, PCI subsystem ID
propagation, and ACPI machine tables for RT721/RT722/RT1320 codec
configurations on both platforms.

Changes in v4:
  - Patch 1: fix missing asoc_sdw_mc_dailink_exit_loop() cleanup on
    devm_kasprintf() failure in acp-sdw-sof-mach.c mc_probe() (new).
  - Patch 2: fix missing asoc_sdw_mc_dailink_exit_loop() cleanup on
    both devm_kasprintf() failure paths in acp-sdw-legacy-mach.c
    mc_probe(); update commit message to reference the correct function
    name soc_card_dai_links_create() instead of sof_card_dai_links_create()
    (new).
  - Patch 3: remove unused ACP63_SDW_MAX_CPU_DAIS define (new).
  - Patch 5 (was 2): add comments above ACP7X_SW_AUDIO* define block
    and get_acp7x_cpu_pin_id() to document the dedicated per-port DMA
    layout and the port-to-use-case mapping.
  - Patch 9 (was 6): replace misleading "No functional change" claim
    with an accurate description of the behavioural change for platforms
    where ignore_internal_dmic is true (dmic_num now stays zero at the
    gate rather than reaching the dmic_num > 0 block).

Changes in v3:
  - Patch 3: update subject and changelog to accurately describe the new
    PDM controller selection infrastructure being added.
  - Patch 5: fix commit subject prefix from "amd: acp7x:" to "amd: acp:"
    since the change is in the generic ACP SoundWire machine driver
    (acp-sdw-sof-mach.c), not the ACP7x-specific SOF driver.

Changes in v2:
  - Patch 6: simplify the DMIC enable condition as suggested by Pierre:
    evaluate the three-way boolean once and nest the ignore_internal_dmic
    check inside, avoiding the double-tested condition from v1.
