As we've discussed on IRC, per Shuah's request, I ended by keeping
one different I/O entity per API type:
#define MEDIA_ENT_F_IO_DTV (MEDIA_ENT_F_BASE + 31)
#define MEDIA_ENT_F_IO_VBI (MEDIA_ENT_F_BASE + 32)
#define MEDIA_ENT_F_IO_SWRADIO (MEDIA_ENT_F_BASE + 33)
#define MEDIA_ENT_F_IO_V4L (MEDIA_ENT_F_OLD_BASE + 1)
