This binding was deprecated due to commitaa381a7259("usb: dwc2: gadget: fix TX FIFO size and address initialization"). However that commit is now reverted, so also revert this commit. The binding is valid and shouldn't be deprecated. This reverts commit65e1ff7f4b("Documentation: devicetree: dwc2: Deprecate g-tx-fifo-size").
