PCI: qcom: Add X1E80100 PCIe support

Add the compatible and the driver data for X1E80100 PCIe controller.

There are 5 controller instances found on this platform, out of which
2 are Gen3 with speeds of up to 8.0GT/s, while the other 3 are Gen4 with
speeds of up to 16GT/s.

The version of the controller is 1.38.0 for all instances, but they are
compatible with 1.9.0 config. The max link width is x8 for one
controller, x4 for two of others and x2 for the two left.
