The Macchitobin board is capable of supplying power up to 2W to SFP
modules. Make that explicit in the device-tree. Without this property
current kernel does not allow SFP modules that require more than 1W.

The Clearfog GT-8K board is capable of supplying power up to 2W to SFP
modules. Make that explicit in the device-tree. Without this property
current kernel does not allow SFP modules that require more than 1W.
