Downgrade camera driver to stock 3.0 kernel one to get rid of HTC extensions

The camera driver taken from Sony Xperia S 6.1.A.0.452 kernel
Add MT9M133 V4L2 driver
Enable MT9M133 camera sensor for TouchPad
Simplify MT9M133 V4L2 driver, fix sensor i2c address, do not reset sensor core registers at startup

Removed unsupported saturation code.

Fixed sensor i2c address to valid (0x78).

I think there's no need to reset the sensor's core registers at
startup. Moreover it requires introducing some delay before we
can set the new values and the msm_sensor interface does not
support such thing right now.

Typo fixes in MT9M113 V4L2 driver

I've made some typo fixes preventing the driver from compiling.
Proper MT9M113 sensor regulators configuration

Use 8058_lvs0 and 8058_l11 regulators for camera
Set CAM_RESET when powering camera
Use clk_prepare_enable/clk_disable_unprepare instead of clk_enable/clk_disable
