V4L/DVB (5474): SN9C1xx driver updates

@ Don't assume that SOF headers can't cross packets boundaries
@ Fix compression quality selection
+ Add support for MI-0360 image sensor
* Documentation updates
@ Fix sysfs
@ MI0343 rewritten
* HV7131R color fixes and add new ABLC control
* Rename the archive from "sn9c102" to "sn9c1xx"
* fix typos
* better support for TAS5110D
@ fix OV7630 wrong colors
@ Don't return an error if no input buffers are enqueued yet on VIDIOC_STREAMON
* Add informations about colorspaces
* More appropriate error codes in case of failure of some system calls
* More precise hardware detection
* Add more informations about supported hardware in the documentation
+ More supported devices
+ Add support for HV7131R image sensor
