[PATCH 06/11] staging: iio: tsl2x7x: make logging consistent and correct newlines

[Brian Masney <masneyb@onstation.org>]

This patch updates all of the logging commands so that they are
consistent with the other messages, includes __func__ in the message,
and all of the messages include newlines. This patch also removes some
debug log messages.

Signed-off-by: Brian Masney <masneyb@onstation.org>

Changes since v1:
- Remove some debug messages and every log message doesn't have to have
  the function name.
- Earlier patches in this current series dropped some of the debug
  messages that were in v1.
