PATCH v3 1/1 w1: Organize driver source to natural/common order

Structures and functions should be ordered such that forward declaration use is minimized.

MODULE_* macros should immediately follow the structures and functions upon which they act.

Remaining MODULE_* macros should be at the end of the file in alphabetical order.
