Add a SoundWire SDCA driver for Senary SN624x multi-function codecs
(jack, speaker amp, and DMIC). Program SDCA SampleFreqIndex in
hw_params, keep SDCA jack IRQs masked with poll-based detection, and
extend the Senary MAINTAINERS entry for the new codec files only.

Add sof_sdw helpers for SN624x jack, amp, and DMIC, and register the
codec_info entries used by the Intel SOF SoundWire machine driver.
Use name_prefix "sn624x" to match UCM and DAI widget naming.

Add SoundWire machine match entries for Senary SN624x on Arrow Lake,
Lunar Lake, Meteor Lake, and Panther Lake, and select the SN624x SDCA
codec from the SOF SoundWire machine Kconfig. Each part ID uses a
separate mach entry; name_prefix is "sn624x".
