+applicable to S900, S700 and S500 SoC's.
Required Properties:
- compatible: should be one of the following,
"actions,s900-cmu"
"actions,s700-cmu"
+ "actions,s500-cmu"
- reg: physical base address of the controller and length of memory mapped
region.
- clocks: Reference to the parent clocks ("hosc", "losc")
