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

Commit 5459c0b7 ("PCI/DPC: Quirk PIO log size for certain Intel Root
Ports") added quirks for Tiger and Alder Lake Root Ports but missed that
the same issue exists also in the previous generation, Ice Lake.

Apply the quirk for Ice Lake Root Ports as well.  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.

[bhelgaas: add dmesg warning and RP PIO Log dump info]
