Subject: [PATCH] [media] ov2659: add v4l2_subdev dependency

The newly added ov2659 driver uses the v4l2 subdev API, but
can be enabled even when that API is not part of the kernel,
resulting in this build error:

media/i2c/ov2659.c: In function 'ov2659_get_fmt':
media/i2c/ov2659.c:1054:8: error: implicit declaration of function 'v4l2_subdev_get_try_format' [-Werror=implicit-function-declaration]
media/i2c/ov2659.c:1054:6: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
media/i2c/ov2659.c: In function 'ov2659_set_fmt':
media/i2c/ov2659.c:1129:6: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
media/i2c/ov2659.c: In function 'ov2659_open':
media/i2c/ov2659.c:1264:38: error: 'struct v4l2_subdev_fh' has no member named 'pad'

This adds an explicit dependency, like all the other drivers have.
