This series adds a initial DT binding doc for ina3221. It defines
a child node to describe the input source of each ina3221 channel.
Then it changes the driver to handle the information properly.

Changelog
v3->v4:
 * Fixed one place in child DT node bindings (PATCH-1)
 * Changed the driver accordingly and added is_visible (PATCH-2)
v2->v3:
 * Fixed two places in DT bindings (PATCH-1)
v1->v2:
 * Redefined DT bindings (detail in PATCH-1)
 * Changed the driver code accordingly (detail in PATCH-2)
