There was no device tree binding in mainline Linux when this driver
was introduced in barebox. This has changed in the mean time, hence
we need to align the clocks and resets in this driver.
This step is a prerequisite for replacing the initial rk3568.dtsi in
arch/arm/dts with the mainline Linux version. For compatibility, the
former is updated accordingly.
