[PATCH] platform/x86/amd/pmc: Add HP Laptop 14-fq1xxx to s2idle quirk list

[Murat Bayraktar via B4 Relay]

From: Murat Bayraktar <bob65536@xxxxxxxxx>

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.
