Roman Gilg bb248490cb Log current planes on apply
It is helpful for debugging to know in which state the available planes on an
output are when a layout is applied that leads to a change.

For that log all planes that are compatible with the output. Currently disabled
planes have multiple properties logged per line to keep the log short.
