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.

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.

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.

When cdns_plat_pcie_probe() succeeds, return success instead of falling
into the error handling code.

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.

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.

Cadence core library files may be used by various platform drivers.
Add a new directory "cadence" to group all the Cadence core library files
and the platforms using Cadence core library.
