drivers: video: i2c: new category to group all sensors

Video processing devices sometimes include external chips often
configured on I2C: sensors, flash, motors, decoders, ISPs...

This commit groups the sensor on a new I2C directory layout akin
to Linux's drivers/media/i2c.

The Kconfig CMakeLists.txt is slightly adjusted for the occasion,
to look like the other drivers directories.
