Since the symbol is also absent from arch/riscv/configs/defconfig, a plain "make defconfig" build for a SpacemiT K1 board ends up with the USB 2.0 PHY driver disabled. dwc3-generic-plat needs that PHY, so the result is a kernel with no working USB at all on boards such as the Milk-V Jupiter, where all four USB 3.0 type-A ports hang off the single dwc3 controller. Give it the same default as its sibling.
