Subject: [PATCH] ASoC: rt286: Generalize support for ALC3263 codec

Git-commit: aa2f9c12821e6a4ba1df4fb34a3dbc6a2a1ee7fe

Patch-mainline: v5.13-rc1

References: git-fixes

The ALC3263 codec on the XPS 13 9343 is also found on the Latitude 13 7350

and Venue 11 Pro 7140. They require the same handling for the combo jack to

work with a headset: GPIO pin 6 must be set.

The HDA driver always sets this pin on the ALC3263, which it distinguishes

by the codec vendor/device ID 0x10ec0288 and PCI subsystem vendor ID 0x1028

(Dell). The ASoC driver does not use PCI, so adapt this check to use DMI to

determine if Dell is the system vendor.
