hwmon: (lm70) Code streamlining and cleanup

This fixes a byteswap bug in the LM70 temperature sensor driver,
which was previously covered up by a converse bug in the driver
for the LM70EVAL-LLP board (which is also fixed).

Other fixes:  doc updates, remove an annoying msleep(), and improve
three-wire protocol handling.
