[PATCH 1/4] dt-bindings: tps65217: Update binding documentation.

[Enric Balletbo i Serra <enric.balletbo@collabora.com>]

This patch adds a new binding documentation for the TPS65217 MFD and
updates the documentation for all the sub-devices in accordance to get
each individual sub-driver functioning correctly.
