ARM: dts: Add sensor and actuator changes to enable sensor

Add actuator regulator property declaration
in the actuator node for msm8916 cdp and
mtp dtsi files.

Remove front sensor's actuator node and imx135 sensor node
from cdp dtsi. There is no actuator for front sensor
and sensor is refered using another node.
Sensor specific node is not needed for bayer sensors.

Remove front actuator node from mtp dtsi as there
is no actuator for front sensor.
