msm: camera: Add DT support in msm sensor for 8974

On 8974, camera sensor is created as a platform device.
platform data is specified in device tree node. Add
support in sensor driver to parse sensor information
from device tree node. Create sensor drivers as platform
driver since CCI hardware controls i2c bus. Also, use
Camera Control Interface (CCI) util functions for I2C
communication.
