[ Upstream commit 83b9296e399367862845d3b19984444fc756bd61 ]

Initialize the four color space fields on the sink and source video pads
of the resizer in the .init_cfg() operation. The resizer can't perform
any color space conversion, so set the sink and source color spaces to
the same defaults, which match the ISP source video pad default.
