ASoC: Intel: soc-acpi: add LG Gram 16Z90U RT713 + single RT1320 quirk 

Add a SoundWire machine table entry for the LG Gram Pro 2026
(16Z90U-KU7BK), which has an unusual configuration:

  sdw:0:1:025d:1320:01   single stereo RT1320 SmartAmp on link 1
  sdw:0:3:025d:0713:01   RT713 jack/headset codec on link 3

Existing rt713-rt1320 boards have two RT1320 amps on different links
("link_mask = BIT(1) | BIT(2) | BIT(3)"). The LG Gram uses a single
stereo RT1320 chip, so the new entry uses "link_mask = BIT(1) |
BIT(3)" with the existing rt1320_1_group2_adr structure, leaving the
two-channel routing to the topology.

The RT713 on this board does not expose a SMART_MIC function in
ACPI, so the .machine_check callback used by the existing entries
(snd_soc_acpi_intel_sdca_is_device_rt712_vb) would reject this
board. Drop machine_check for the new entry; speaker output and
the headset jack do not depend on the SMART_MIC presence check.

The corresponding topology source has been submitted to the SOF
project at https://github.com/thesofproject/sof/pull/10760

 . The
generated sof-ptl-rt713-l3-rt1320-l1-2ch.tplg and
nhlt-sof-ptl-rt713-l3-rt1320-l1.bin will follow in linux-firmware
once that lands.

Tested on Ubuntu 26.04 with kernel 7.0.0-15: speaker (RT1320
stereo), headphone jack with auto-routing, headset mic, and the
internal NHLT DMIC array all work via the UCM HiFi profile.
