ARM: dts: msm: Add PCIe switch driver for sdxprairie 



Use the errata property to pass the corresponding
configuration to be run on the diode switch connected
to the PCIe root port. The errata programs the corresponding
port based on the bus, device and function of the switch port.
Update the IOMMU SID to reflect the change in ordering due
to the addition of the switch. The end point devices have
their own PCIe IOMMU SID group to avoid conflicts with each other.
