drm/amd/display: For ODM seamless transition require AUTO mode
[Why & How]
ODM seamless transitions require DIV_MODE_AUTO. However,
DIV_MODE_AUTO only works when all the horizontal timing params
are divisible by the ODM combine factor. Therefore, disable the
ODM 2:1 policy when the horizontal timing params are not divisible
by 2.
