Commit cefdd52fa04 ("usb: dwc3: dwc3-qcom: Enable tx-fifo-resize
property by default") added the tx-fifo-resize property. But when this
property exists already, of_add_property() fails with -EEXIST, thus
breaking core registration. This regresses the IPQ6018 platform that has
tx-fifo-resize in its device-tree.
Don't fail when tx-fifo-resize exists.
