From: Murat Bayraktar <bob65536@proton.me>

The HP Laptop 14-fq1xxx (board 887C, BIOS F.38) takes about 10.2
seconds in noirq device resume from s2idle. Its firmware uses the NVMe
SMI path already handled by amd_pmc_skip_nvme_smi_handler().

Add the system to fwbug_list with the combined Cezanne quirk so the
existing spurious 8042 workaround remains enabled. This reduced noirq
device resume from 10195/10242 ms to 27 ms in testing.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

FYI [if applicable to your patch], as per Linus' policy change, also
fixes are mostly routed through for-next unless the fix is for a
commit introduced in the most recent cycle or is clearly a regression
fix.
