PCI: Add ACS quirk for Pericom PI7C9X2G404 switches [12d8:b404]
[ Upstream commit 5907a90551e9f7968781f3a6ab8684458959beb3 ]
12d8:b404 is apparently another PCI ID for Pericom PI7C9X2G404 (as
identified by the chip silkscreen and lspci).
It is also affected by the PI7C9X2G errata (e.g. a network card attached
to it fails under load when P2P Redirect Request is enabled), so apply
the same quirk to this PCI ID too.
PCI bridge [0604]: Pericom Semiconductor PI7C9X2G404 EV/SV PCIe2 4-Port/4-Lane Packet Switch [12d8:b404] (rev 01)
Fixes: acd61ffb2f16 ("PCI: Add ACS quirk for Pericom PI7C9X2G switches")
