Alexander Stein ee31742bf1 drm/imx/ipuv3: Fix front porch adjustment upon hactive aligning
When hactive is not aligned to 8 pixels, it is aligned accordingly and
hfront porch needs to be reduced the same amount. Unfortunately the front
porch is set to the difference rather than reducing it. There are some
Samsung TVs which can't cope with a front porch of instead of 70.
