Subject: [PATCH] PCI/DPC: Yet another quirk for PIO log size on Intel Raptor Lake-P

There is yet another PCI entry for Intel Raptor Lake-P that shows the
  error "DPC: RP PIO log size 0 is invalid":
  0000:00:07.0 PCI bridge [0604]: Intel Corporation Raptor Lake-P Thunderbolt 4 PCI Express Root Port #0 [8086:a76e]
  0000:00:07.2 PCI bridge [0604]: Intel Corporation Raptor Lake-P Thunderbolt 4 PCI Express Root Port #2 [8086:a72f]

Add the corresponding quirk entry for 8086:a72f.

Note that the one for 8086:a76e has been already added by the commit
627c6db20703 ("PCI/DPC: Quirk PIO log size for Intel Raptor Lake Root
Ports").
