d07701a17a 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.

7a790087c1 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.

de80f95ccb PCI: cadence: Move all files to per-device cadence directory
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.
