TMP108 is powered by its V+ supply, document it.
While at it, add a short description with a link to its datasheets.

Not entirely sure of the "v+-supply" name, but the datasheet only ever
refers to it as "V+" or simply as the "supply voltage".
Only other name I've seen is in the schematic for the msm8226-based
motorola-falcon smartphone, where it's called "V_POS".

Guess one has to praise the ability of datasheet writers to come up
with different names.

The datasheet for tmp117 also uses the V+ term, yet the supply name
is "vcc-supply". I would personally very much prefer to stick with that,
but that is just my personal opinion.

I'm okay with that. I'll keep this for a few days to see if anyone else
has anything to say, then I'll send a V2 with it changed to vcc.

vcc. Anyway + is not an expected character.
