mm-video: Amend stride and scanlines according to the color format

The stride and scanlines are updated to client according to the
color format supported by the video hardware with which third party
applications output is improper even though standard YUV planar
color format is set to the video component.
The issue was resolved by updating stride and scanlines values
equal to the standard YUV planar color format.
