Subject: [PATCH 0/3] riscv: jh7110: Fix configuration for on-chip USB 2.0 support

While mainline has support for the USB controller of the JH7110 since 6.5,
this never really worked, even not with latest downstream kernels by Starfive -
unless you were also using an old downstream U-Boot version. The reason for
that was a missing syscon setting that prevented the connection between USB
2.0 PHY and the controller. This series finally fixes the issue.
