[GIT PULL v2 FOR v4.10] Media IOCTL handling rework

[Sakari Ailus]

Hi Mauro,

These four patches rework Media controller IOCTL handling for cleanups and      
preparation for variable sized IOCTL arguments.                                 
                                                                                
What's changed since the previous set is that the compat handling is kept
as-is, i.e. it simply calls the regular handler if the IOCTL is something
else than MEDIA_IOC_ENUM_LINKS32.

Please pull.
