I think I now understand what is going wrong.

Before the offending patch, the PHY was simply initialized by u-boot
and continued running.

Now, with this patch, the USB subsystem expects that the linux kernel
driver can initialize and provide the phy. Which fails (even before the
patch was applied) because the usb0_phy clock has some bug.

The question is what is missing or wrong there. It should have been
fixed upstream and others should have noticed the same issue...
