media: i2c: mt9t112: Remove soc_camera dependencies
Remove soc_camera framework dependencies from mt9t112 sensor driver. - Handle clk, gpios and power routines - Register async subdev - Remove deprecated g/s_mbus_config operations - Remove driver flags - Change driver interface and add kernel doc - Adjust build system - Fix code style issues reported by checkpatch in strict mode This commit does not remove the original soc_camera based driver as long as other platforms depends on soc_camera framework. As I don't have access to a working camera module, this change has only been compile tested.
