This series adds device tree support for the Thundercomm RB5Gen2
development kit, based on the Qualcomm QCS8550 chipset.

Patches 1-3 prepare the SM8550 device tree by adding MHI register regions
and port labels to the PCIe controller nodes, then update the existing
HDK and QRD board files to match the renamed labels.

Patches 4-5 add the dt-bindings documentation and the board device tree
for the RB5Gen2. This initial submission covers the main board; the vision
mezzanine will be supported in a follow-up series.
