The Active-semi ACT8945A PMIC is a Multi-Function Device, it has
two subdevices:
 - Regulator
 - Charger

This patch adds documentation for ACT8945A DT bindings.

Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com>
Acked-by: Rob Herring <robh@kernel.org>

Changes in v7: None
Changes in v6:
 - change the regulator name.

Changes in v5: None
Changes in v4: None
Changes in v3:
 - fix the tabbing errors in Example.
 - use "pmic@5b" label, not "act8945a@5b" in Example.
 - collect Acked-by from Rob.

Changes in v2:
 - use more specific label in Example.
 - add pmic and charger nodes in Example.
