Accrording the SDK from Allwinner, the scanline value of yuv and rgb for
V3s are both 1024. The is also the same for mixer 1 of D1. Currently the
scanline value of rgb is hardcoded to 2048 for all SOCs.

Change the scanline_yuv property of V3s to 1024. Add the scanline_rgb
property to the mixer config and replace the hardcoded value with it before
scaling.
