Changes in V2:
 - As per Stephen's comments, replaced '_' with '-' for node names.

Changes in V3:
 - Changed the regulator node names as l1, l2 etc
 - Changed "pm8008-regulators" to "regulators"
 - Changed "qcom,min-dropout-voltage" to "regulator-min-dropout-voltage-microvolt"

Changes in V4:
 - Moved all common stuff to pm8008.dtsi and added board specific configurations here.

Changes in V5:
 - Changed the node names as per pm8008.dtsi
 - Moved supply nodes to chip level (mfd node).
 - Removed the regulator-mindropout property.

Changes in V6:
 - No changes.
