iio: ina2xx: Fix whitespace and re-order code
Group of probably overly rigorous whitespace and code cleanups. - Alphabetize includes - Assign to variables in the order they are defined - Alignment issues - Group alike statements together - Use helper macros Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
