msm: camera: reimplement camera sensor driver
Camera sensor driver architecture is redesigned to have move control
at user space. The current kernel driver has provision for probing
to find whether a particular camera sensor is connected. A video node
is created for every successful camera probe. This request consists of
samsung S5K3L1YX 12 MP sensor driver, CCI (Camera Control Interface)
driver to perform I2C calls on I2C master bus, I2C MUX driver to select
2D / 3D MUX, QUP driver to perform legacy I2C calls and other utility
functions (msm_sensor) that can be reused by kernel sensor drivers.
