I actually started applying this last night (see [1]), but got some
errors from the build-bot (attached).  I haven't looked into them,
but my guess is that you're missing a Kconfig dependency or something
equally minor.

commit: a58f3d0c3b1c4a71a2418c3306fba86c26a49781 [1/1] PCI: xilinx: Add Xilinx 
PCIe Host Bridge IP driver

All warnings:

>> WARNING: drivers/built-in.o(.text+0x64acc): Section mismatch in reference

   The function xilinx_pcie_probe() references
   the function __init xilinx_pcie_scan_bus().
   This is often because xilinx_pcie_probe lacks a __init
   annotation or the annotation of xilinx_pcie_scan_bus is wrong.
