[PATCH v2 1/3] dt-bindings: pci: ti, j721e: Fix "ti, syscon-pcie-ctrl" to take argument

[Kishon Vijay Abraham I]

Fix binding documentation of "ti,syscon-pcie-ctrl" to take phandle with
argument. The argument is the register offset within "syscon" used to
configure PCIe controller. This change is as discussed in [1]

Fixes: 431b53b81cdc ("dt-bindings: PCI: Add host mode dt-bindings for TI's J721E SoC")
Fixes: 45b39e928966 ("dt-bindings: PCI: Add EP mode dt-bindings for TI's J721E SoC")
