This compatible makes no sense, we shouldn't be marking a full HW block with
some name that is just intended for LIODN convenance.
Is this version 3 of the block? If so a name like "fsl,maple-v3" or
"fsl,maple-v3.0" would be more appropriate.

Does Maple not have any IRQs associated with it?
If you are going to have a minimal binding, at least cover the basics
associated with a device.
