LTDC 40100 hw version supports the YCbCr 422 output,
reducing the output pins from 24 to 16. This feature
is useful for some external devices like HDMI bridges.
Both ITU-R BT.601 & ITU-R BT.709 are supported.
It is also possible to choose the chrominance order between
* Cb is output first (Y0Cb, then Y1Cr, Y2Cb and so on).
* Cr is output first (Y0Cr, then Y1Cb, Y2Cr and so on).
