Update the links to the datasheet of some of the devices supported by
the lm90 driver. Also remove the links from the driver itself, so that
we don't have to update them twice each time they change.

The Maxim MAX6657, MAX6658 and MAX6659 have extra resolution bits for
the local temperature measurement. Let the lm90 driver read them and
export them to user-space.

Add PEC support to the lm90 driver. Only the ADM1032 chip supports it,
and in a rather tricky way, which is why this patch comes with
documentation reinforcements. At least, this demonstrates that the new
PEC support logic in i2c-core can properly deal with chips with partial
PEC support.
As enabling PEC causes a significant performance drop, it can be
disabled through a sysfs file (unsurprisingly named "pec").

Part 3: Move the drivers documentation, plus two general documentation
files.
Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.
