The rockchip,rk3328-cru.txt file was converted to YAML.
A DT test of the rk3328 cru node gives notifications regarding
the compatible string. Bring it in line with the binding by
removing some unused fall back strings.

Are you sure these are unused? rockchip,cru maybe, but what about DTS
used out of tree? It's useful to mention that the compatible is not
documented (so if there are any out of tree users, it's their fault).

Removal of syscon is different case - why do you think it is unused? Did
you check it? It's not a fallback compatible.

Hi,

If someone knows why that was added to the Rockchip tree? Let us
know.(Elaine ??)
Other well know locations don't seem to use it.

Please advise.
