Does this make sense to even be a separate bool device tree property?
This sort of configuration is typically done by:
1. Creating a new 'caps' bit; relevant codepaths check that bit
2. Creating a new "compatible" string for your platform's macb
instance
3. Creating a new 'struct macb_config' instance for your platform,
setting any relevant caps bits when it is selected.
