Subject: [PATCH V13 2/9] dt-bindings: mfd: pm8008: Change the address cells

Change the address cells as '2' so that the first cell
describes the i2c address offset of the clients.
This helps us to define the child nodes of all
clients under the same parent mfd node, instead of
adding separate mfd DT nodes.

Change the gpios reg value accordingly.
