Also, we don't want to encourage the pattern of wrapper nodes just to define resources such as clocks, resets, power-domains, etc. when not necessary.

The intent was to modify the RK3399 DTs to use a single node, but the DT changes were rejected for ABI reasons. However, the schema was accepted as-is. To fix this, we need to move the RK3399 binding to its own schema file. The RK3328 and RK3568 bindings are correct and use a single node.
