PCI/DPC: Quirk PIO log size for Intel Raptor Lake-P
[ Upstream commit b198499c7d2508a76243b98e7cca992f6fd2b7f7 ]
Apparently the Raptor Lake-P reference firmware configures the PIO log size
correctly, but some vendor BIOSes, including at least ASUSTeK COMPUTER INC.
Zenbook UX3402VA_UX3402VA, do not.
Apply the quirk for Raptor Lake-P. This prevents kernel complaints like:
DPC: RP PIO log size 0 is invalid
and also enables the DPC driver to dump the RP PIO Log registers when DPC
is triggered.
Note that the bug report also mentions 8086:a76e, which has been already
added by 627c6db20703 ("PCI/DPC: Quirk PIO log size for Intel Raptor Lake
Root Ports").
