Fix all this by reworking the set format operation as follows: 1. For the source pad, turn set() into get() as the source format is not modifiable. 2. Validate the requested format and updated the stored format accordingly. 3. Return the format actually set. 4. Propagate the format from sink to source.

This leads to hard to read lines such as return enum_format(fourcc, NULL, index, cs_sel, true, false); where the boolean parameters can easily be mixed. To make the code clearer, add a CS_SEL_BAYER flag that can be passed through the codespace_sel parameter of the lookup functions to replace the bool parameter.

This complicates the lookup and enumeration function without really increasing efficiency, as both tables contain a single element. Merge the two tables and simplify the functions, and move the resulting table next to the functions that use it.

The functions dealing with the imx_media_pixfmt structures assume that the array of codes is terminated by a 0 elements. This mechanism is fragile, as demonstrated by several instances of the structure contained 4 non-zero codes. Fix this by turning the array into a pointer, and providing an IMX_BUS_FMTS macro to initialize the codes member with a guaranteed 0 element at the end.

This aligns the naming scheme with the media bus and IPU format functions that already end with *_mbus_format() and *_ipu_formats(). - Rename all enumeration functions to pluralize 'formats' at the end, as they enumerate multiple formats.
