[ Upstream commit 8ec017cf31299c4b6287ebe27afe81c986aeef88 ]

The HP Laptop 15-fc0xxx (subsystem ID 0x103c8dc9) has an internal
DMIC connected to the AMD ACP6x audio coprocessor. Add a DMI quirk
entry so the internal microphone is properly detected on this model.

Tested on HP Laptop 15-fc0237ns with Fedora 43 (kernel 6.19.9).
