Current USB fastboot functionality from U-Boot proper in master is broken
on Verdin iMX8M Plus since commit b4734c9c333b ("clk: imx: Convert
clock-osc-* back to osc_*"). Other i.MX SoCs might be affected, I have
not looked into every detail.

Reverting this commit on top of master is not trivial (there are
conflicts, and I have not looked into the details).
