soc/mediatek/mt8188: Fix USB2 detection issue
MT8188 supports port0/port1 download. The hardware needs a trapping pin to select the port to use. When port1 is selected, the phy of port1 will be switched to port0. That is, port1 connector will be the physical line of port0. Since port0 phy isn't initialized in coreboot, switch back to port1 phy. BUG=b:269059211 TEST=can detect USB2 devices in depthcharge.
