ASoC: Intel: sof_sdw: Add lookup of quirk using PCI subsystem ID

Add lookup of PCI subsystem vendor:device ID to find a quirk.

The subsystem ID (SSID) is part of the PCI specification to uniquely
identify a particular system-specific implementation of a hardware
device.

Unlike DMI information, it identifies the sound hardware itself, rather
than a specific model of PC. SSID can be more reliable and stable than
DMI strings, and is preferred by some vendors as the way to identify
the actual sound hardware.
