[PATCH] dt-bindings: hwmon: ti,tmp108: document V+ supply, add short description

[Stanislav Jakubek]

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".
