Adds "linux,pci-domain" as required proptery for iMX8MQ to indicate pci controller index. This adjustment paves the way for eliminating the hardcoded check on the base register for acquiring the controller_id. ... if (dbi_base->start == IMX8MQ_PCIE2_BASE_ADDR) imx6_pcie->controller_id = 1; ... The controller_id is crucial and utilized for certain register bit positions. It must align precisely with the controller index in the SoC. An auto-incremented ID don't fit this case. The DTS or fuse configurations may deactivate specific PCI controllers.
