dt-bindings: PCI: ti,am65: Fix "ti,syscon-pcie-id"/"ti,syscon-pcie-mode" to take argument
Fix binding documentation of "ti,syscon-pcie-id" and "ti,syscon-pcie-mode"
to take phandle with argument. The argument is the register offset within
"syscon" used to configure PCIe controller. Similar change for j721e is
discussed in [1]
