Widen sof-firmware install to all Intel SOF audio platforms

The sof-audio-pci-intel-* driver family needs sof-firmware to boot the
DSP, but mainline linux only optdeps it, so affected installs came up
with a Dummy Output sink only. Replace the Panther Lake check with
omarchy-hw-intel-sof, which detects any Intel PCI audio controller.

Ports ffa81021 from master, which adapts basecamp/omarchy#6200.
