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.
