[media] media: i2c/soc_camera: fix ov6650 sensor getting wrong clock
After changes to v4l2_clk API introduced in v4.1 by commitsa37462b919
'[media] V4L: remove clock name from v4l2_clk API' and4f528afcfb
'[media] V4L: add CCF support to the v4l2_clk API', ov6650 sensor stopped responding because v4l2_clk_get(), still called with depreciated V4L2 clock name "mclk", started to return respective CCF clock instead of the V4l2 one registered by soc_camera. Fix it by calling v4l2_clk_get() with NULL clock name. Created and tested on Amstrad Delta against Linux-4.7-rc3 with omap1_camera fixes.
