media: ov2680: Remove VIDEO_V4L2_SUBDEV_API ifdef-s

VIDEO_V4L2_SUBDEV_API is now automatically selected in Kconfig
for all sensor drivers. Remove the ifdef CONFIG_VIDEO_V4L2_SUBDEV_API
checks.

This is a preparation patch for fixing ov2680_set_fmt()
which == V4L2_SUBDEV_FORMAT_TRY calls not properly filling in
the passed in v4l2_mbus_framefmt struct.
