arm64: dts: rockchip: disable tx ipgap linecheck for rk3399 dwc3 RK3399 USB DWC3 controller has a issue that FS/LS devices not recognized if inserted through USB 3.0 HUB. It's because that the inter-packet delay between the SSPLIT token to SETUP token is about 566ns, more then the USB spec requirement. This patch adds a quirk "snps,dis-tx-ipgap-linecheck-quirk" to disable the u2mac linestate check to decrease the SSPLIT token to SETUP token inter-packet delay from 566ns to 466ns.
