powerpc/fsl-pci: Add generic code to setup PCIe controllers
Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled. After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.
We also provide a per controller (rather than all) for some systems that
may have special requirements.
Finally, we refactor the code used by the P1022DS to utilize the new
generic code.
