PCI: cadence: Drop unused member from struct cdns_plat_pcie The struct cdns_plat_pcie contains a member called is_rc that is not being used beyond being assigned a value within the cdns_plat_pcie_probe() function, which is then not used for anything. Thus, drop is_rc from the struct cdns_plat_pcie, especially since there already is an is_rc member within the struct cdns_plat_pcie_of_data that is actively used to convey information about the PCIe controller mode.

PCI: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

PCI: cadence: Prefer of_device_get_match_data() The cadence driver only needs the device data, not the whole struct of_device_id. Use of_device_get_match_data() instead of of_match_device(). No functional change intended.

PCI: cadence: Add new *ops* for CPU addr fixup Cadence driver uses "mem" memory resource to obtain the offset of configuration space address region, memory space address region and message space address region. The obtained offset is used to program the Address Translation Unit (ATU). However certain platforms like TI's J721E SoC require the absolute address to be programmed in the ATU and not just the offset. Add new *ops* for CPU addr fixup for the platform drivers to provide the correct address to be programmed in the ATU.

PCI: cadence: Fix runtime PM imbalance on error pm_runtime_get_sync() increments the runtime PM usage counter even it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.
