pci1xxxx is a PCIe switch with a multi-function endpoint on one of its
downstream ports. Quad-uart is one of the functions in the multi-function
endpoint. This patch adds device driver for the quad-uart function and
enumerates between 1 to 4 instances of uarts based on the PCIe subsystem
device ID.

The changes from v1->v2->v3->v4->v5->v6->v7->v8->v9->v10 are mentioned in
each patch in the patchset.

Thanks to Andy Shevchenko, Ilpo Jarvinen, Chritophe JAILLET, Geert
Uytterhoeven, Greg KH, Jiri Slaby for their review comments.

This doesn't apply to my tree anymore.  Can you rebase it against
Linus's latest, or linux-next and resend?

thanks,
