PCI/DPC: Quirk PIO log size for Intel Raptor Lake Root Ports

[ Upstream commit 627c6db2 ]

Commit 5459c0b7 ("PCI/DPC: Quirk PIO log size for certain Intel Root
Ports") and commit 3b880349 ("PCI/DPC: Quirk PIO log size for Intel Ice
Lake Root Ports") add quirks for Ice, Tiger and Alder Lake Root Ports.
System firmware for Raptor Lake still has the bug, so Linux logs the
warning below on several Raptor Lake systems like Dell Precision 3581 with
Intel Raptor Lake processor (0W18NX) system firmware/BIOS version 1.10.1.

  pci 0000:00:07.0: [8086:a76e] type 01 class 0x060400
  pci 0000:00:07.0: DPC: RP PIO log size 0 is invalid
  pci 0000:00:07.1: [8086:a73f] type 01 class 0x060400
  pci 0000:00:07.1: DPC: RP PIO log size 0 is invalid

Apply the quirk for Raptor Lake Root Ports as well.

This also enables the DPC driver to dump the RP PIO Log registers when DPC
is triggered.
