Works for me — and it should be inert outside the AMD units: the "21C"
prefix also spans the Intel siblings of the L14/L15 Gen 3 family, but
amd_pmc never binds on those (no AMDI0005 ACPI node exposed by their
firmware), so the widened match can only ever fire on the AMD types
anyway.

Happy to resend as a modification of the existing entry if that's the
preferred shape.

For reference, the v2 as sent was tested on 21C5S05800, BIOS R1YET62W
(1.39), kernel 7.2.8: the 7-10 s resume stall is gone (kernel resume
in under 100 ms, A/B tested against the stock module on the same boot).

Regards,
Bruno
