Adding of dditional support to Cadence PCIe controller (i.e. pci-j721e.c)
for up to 4x lanes, and reworking of driver to define maximum lanes per
board configuration.
Changes from v1:
* Reworked 'PCI: j721e: Add PCIe 4x lane selection support' to not cause
regressions on 1-2x lane platforms
Changes from v2:
* Correct dev_warn format string from %d to %u since lane count is a unsigned
integer
* Update CC list
Changes from v3:
* Use the max_lanes setting per chip for the mask size required since bootloader
could have set num_lanes to a higher value that the device tree which would leave
in an undefined state
* Reorder patches do the previous change to not break bisect
* Remove line breaking for dev_warn to allow better grepping and since no strict
80 columns anymore
Changes from v4:
* Correct invalid settings for j7200 PCIe RC + EP
* Add j784s4 configuration for selection of 4x lanes
