[PATCH 2/2] ASoC: intel: ptl: Add machine driver entry for Dell XPS 14 DA14260

[John Meyer <jmeyer@fdma.com>]

The Dell XPS 14 DA14260 (Panther Lake) uses the following SoundWire
audio topology:

  Link 0: CS42L45 (mfr 0x01FA, part 0x4245) -- SDCA headset codec
            ADR 0x00003001FA424501
            Endpoints: UAJ (jack playback), SmartMic (DMIC), UAJ (jack
            capture)

  Link 2: Two CS35L57 speaker amps (mfr 0x01FA, part 0x3557)
            ADR 0x00023201FA355701 (left/AMP1)
            ADR 0x00023301FA355701 (AMP2)

  Link 3: Two CS35L57 speaker amps
            ADR 0x00033001FA355701 (right/AMP3)
            ADR 0x00033101FA355701 (AMP4)

ADR values were obtained from the platform ACPI DSDT.

Add the necessary ADR device arrays, endpoint descriptors, link array,
and machine table entry.  The CS42L45 uses three non-aggregated
endpoints (jack playback/capture and DMIC) matching the SDCA functions
advertised by the hardware.  The four CS35L57 amps use the existing
aggregated speaker endpoint descriptors (spk_l, spk_2, spk_r, spk_3).

The topology file name follows the established PTL naming convention.
Note: a PTL-specific topology file does not yet exist; users can
symlink sof-lnl-cs42l43-l0-cs35l56-l23.tplg as a workaround until
a dedicated PTL topology is submitted to linux-firmware.

Tested on Dell XPS 14 DA14260 (Panther Lake, kernel 6.18.20).
