Subject: [PATCH v2] dt-bindings: hwmon: ti,tmp108: document V+ supply, add
 short description

TMP108 is powered by its V+ supply, document it. The property is called
"vcc-supply" since the plus sign (+) is not an expected character.
While at it, add a short description with a link to its datasheets.

Changes in V2:
  - rename "v+-supply" to "vcc-supply"
  - add a short description clarifying that vcc is actually V+
  - update commit message to reflect this change
