The required driver support for USB 2.0 landed in v2025.07 and USB 3.0
in v2025.10. It is now only the DT nodes (on Linux ML) that is missing
to make USB work for this and other RK3528 boards.

USB has been working as it should for this and the other rk3528 boards
with my rk3528 branch [1] for the past 5-7 months, so I would very much
prefer to enable these Kconfig options now and just have wait for a
future DT pick or sync to make USB finally work in upstream.
