drm/rockchip: vop: correct the source size of uv scale factor setting
When the input color format is YUV, we need to do some external scale
for CBCR. Like,
* In YUV420 data format:
cbcr_xscale = dst_w / src_w * 2;
cbcr_yscale = dst_h / src_h * 2;
* In YUV422 data format:
cbcr_xscale = dst_w / src_w * 2;
cbcr_yscale = dst_h / src_h;
* In YUV444 data format
cbcr_xscale = dst_w / src_w;
cbcr_yscale = dst_h / src_h;
