USB: isd200: sort out USB/IDE dependancy mess

The ISD200 driver imports a single trivial routine from the IDE layer and
in doing so creates a mess of dependancies that drag in the entire old
IDE layer. Even more sad - it does this for a routine which is usually
(little endian) a null function!

- Copy the function into ISD200
- Rename it so it doesn't clash with the ide header prototype
- Remove all the depend constraints
