device: untangle device_t from struct device some more 

This further allows compilation units to be re-used without
having to add macro guards because of declarations not being
around in the __SIMPLE_DEVICE__ case. These declarations are for
functions that operate on struct device. struct device is a known
type so just expose the functions using the correct type. Also,
DEVTREE_CONST is empty while in ramstage so there's no reason
to separate the declarations. They compile regardless of stage.
