This makes ltr501 code consistent with the coding style adopted
for the new drivers added to IIO.
We prepare the path for adding support for LTR559 chip.

Changes since v1:
* rebased on top of 1ca510b0ea6 ("iio: light: ltr501: Powerdown device on error")
* separated from path series related to LTR559 support because there are still things
to do there: http://marc.info/?l=linux-kernel&m=142779827617036&w=2
