Modernise the documentation to make it more precise and update the use of
pixel rate control and various other changes. In particular:
- Use non-proportional font for file names, properties as well as
controls.
- The unit of the HBLANK control is pixels, not lines.
- The unit of PIXEL_RATE control is pixels per second, not Hz.
- Merge common requirements for CSI-2 and parallel busses.
- Include all DT properties needed for assigned clocks.
- Fix referencing the link rate control.
- SMIA driver's new name is CCS driver.
- The PIXEL_RATE control denotes pixel rate on the pixel array on camera
sensors. Do not suggest it is used to tell the maximum pixel rate on the
bus anymore.
- Improve ReST syntax (plain struct and function names).
- Remove the suggestion to use s_power() in receiver drivers.
- Make MIPI website URL use HTTPS, add Wikipedia links to BT.601 and
BT.656.

Remove extra "is" from sentence explaining V4L2_CID_PIXEL_RATE may be used
to tell the pixel rate used by a transmitter driver. Also call
V4L2_CID_PIXEL_RATE a control.

While we have had some example drivers, there has been up to date no
formal documentation on how camera sensor drivers should be written; what
are the practices, why, and where they apply.

The media bus formats to be used on serial busses are documented but there
was no reference from CSI-2 documentation. Add that now.

All those documents describe the media driver API. So, move
them to the right place within the Kernel documentation.
