[SRU][R][PATCH 0/3] ASoC: enable rt1320 speaker amp and DMIC on PTL SoundWire platforms

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/2150196

SRU Justification:

[ Impact ]
Lenovo PTL systems with rt722 headset codec + rt1320 speaker amp over
SoundWire have no speaker audio and no DMIC. The kernel's PTL match
table lacks the rt722_l0_rt1320_l23 topology, the rt1320
codec_info_list is missing its DMIC dai, and the is_amp flag is
absent -- so the machine driver never matches and the wrong name
prefix is assigned.

[ Fix ]
Three upstream commits from Linus's mainline tree for resolute,
1. 9033f7b7f27d -- drop rt722 monolithic match tables
2. dd4a1963ddf0 -- add is_amp flag to fix wrong name prefix
3. ae2cb3384337 -- add rt1320/rt1321 DMIC dai in codec_info_list

All cherry-pick cleanly with zero conflicts. Diffs are byte-identical
to upstream (only index hashes and hunk offsets differ due to different
base tree).

[ Test Plan ]
On a Lenovo PTL system with spk:rt1320 + hs:rt722:
1. Boot without patches: no speaker sound card components, no DMIC
2. Boot with patches:
   - Speaker playback: aplay -D hw:0,2 tone.wav
   - DMIC loopback: play 1kHz tone through speaker, record from DMIC,
     FFT confirms peak at 1000 Hz
   - WirePlumber sees all devices
   - Mute LEDs functional (speaker and mic)
   - Suspend/resume: full status diff pre vs post identical, loopback
     and LEDs work after resume

[ Where problems could occur ]
Patches touch PTL match tables, SoundWire codec_info_list, and SOF
HDA codec matching. A wrong match table entry could cause a different
PTL topology to break (wrong codec matched). The is_amp flag override
in find_acpi_adr_device() runs for all SoundWire codecs on Intel SOF
platforms -- if the flag logic is wrong, non-amp codecs could get
misidentified, breaking name prefixes and DAI routing. Commits 4-5
remove rt721/rt722 monolithic match tables; any PTL machine still
relying on monolithic matching (rather than function topologies)
would lose its match entry.

[ Other Info ]
Since the hardware is only fully supported from 6.17 kernel,
SRU for resolute and oem-6.17 and resolute only.
