PCI/DPC: Quirk PIO log size for Intel Raptor Lake-P

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").
