The MSI Crosshair A16 HX (D8WFKG) uses a Ryzen 9 8940HX processor,
which identifies with ACP PCI revision 0x62. This revision is currently
unlisted in the Pink Sardine driver, causing the probe to return -ENODEV.

Furthermore, the MSI BIOS lacks the necessary 'acp-audio-device-type'
and '_WOV' ACPI entries required to automatically route the internal
digital microphone array.

Add the 0x62 revision to the PCI validation switch block, and introduce
a DMI quirk table to manually force the PDM configuration flag for this
specific board, allowing the acp63-dmic-capture node to map correctly.
