Two blocks on SpacemiT K1 boards are unreachable from a stock defconfig
build:
- USB_DWC3 is not enabled, so the dwc3 controller that drives all of
the USB 3.0 ports on boards like the Milk-V Jupiter never probes.
- SPACEMIT_K1_TSENSOR has no default in its Kconfig and is not listed
here, so a K1 board comes up with no temperature readings at all,
even though k1.dtsi describes five thermal zones.
Enable both.

The patch itself looks good to me, but since it deal with two diferent drivers
So, can you split it into two patches? which easy to review and manage
