[PATCH] media: staging: max96712: add V4L2 dependencies

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Without the extra dependencies, I run into randconfig build failures:

WARNING: unmet direct dependencies detected for VIDEO_V4L2_SUBDEV_API
  Depends on [n]: MEDIA_SUPPORT [=y] && VIDEO_DEV [=n] && MEDIA_CONTROLLER [=y]
  Selected by [y]:

Hi Arnd,

Thanks for your patch.

I'm sorry for introducing the fault in the first place, Sakari already 
sent a fix for my mistake [1]. Just waiting for Mauro to pick it up.
