PCI: j721e: Get offset within "syscon" from "ti,syscon-pcie-ctrl" phandle arg
Get "syscon" pcie_ctrl offset from the argument of "ti,syscon-pcie-ctrl"
phandle. Previously a subnode to "syscon" node was added which has the
exact memory mapped address of pcie_ctrl but now the offset of pcie_ctrl
within "syscon" is now being passed as argument to "ti,syscon-pcie-ctrl"
phandle.
If the offset is not provided in "ti,syscon-pcie-ctrl", the
full memory mapped address of pcie_ctrl is used in order to maintain old
DT compatibility.
