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->v11 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.

LKP is not happy, perhaps you forgot to use --base.
