Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

-/* Sub-devices are devices that are connected somehow to the main bridge
-   device. These devices are usually audio/video muxers/encoders/decoders or
-   sensors and webcam controllers.
-
-   Usually these devices are controlled through an i2c bus, but other busses
-   may also be used.
-
-   The v4l2_subdev struct provides a way of accessing these devices in a
-   generic manner. Most operations that these sub-devices support fall in
-   a few categories: core ops, audio ops, video ops and tuner ops.
-
-   More categories can be added if needed, although this should remain a
-   limited set (no more than approx. 8 categories).
-
-   Each category has its own set of ops that subdev drivers can implement.
-
-   A subdev driver can leave the pointer to the category ops NULL if
-   it does not implement them (e.g. an audio subdev will generally not
-   implement the video category ops). The exception is the core category:
-   this must always be present.
-
-   These ops are all used internally so it is no problem to change, remove
-   or add ops or move ops from one to another category. Currently these
-   ops are based on the original ioctls, but since ops are not limited to
-   one argument there is room for improvement here once all i2c subdev
-   drivers are converted to use these ops.
- */
-
-/* Core ops: it is highly recommended to implement at least these ops:
-
-   g_chip_ident
-   log_status
-   g_register
-   s_register
-
-   This provides basic debugging support.
-
-   The ioctl ops is meant for generic ioctl-like commands. Depending on
-   the use-case it might be better to use subdev-specific ops (currently
-   not yet implemented) since ops provide proper type-checking.
