PCI: Add function 1 DMA alias quirk for Marvell 88SE9235

commit 88d341716b83abd355558523186ca488918627ee upstream.

Marvell's own product brief implies the 92xx series are a closely related
family, and sure enough it turns out that 9235 seems to need the same quirk
as the other three, although possibly only when certain ports are used.
