In 8b mode, Vertically Ancillary Data typically resides in the Luma
sites. This bit allows vertical ancillary data to be extracted from the
chroma sites instead.
00 = Extract 8b Mode Vertical Ancillary Data from Luma Sites
01 = Extract 8b Mode Vertical Ancillary Data from Chroma Sites
10, 11 = Extract every single sample of vertical ancillary data
The output line is twice as wide as the other modes. For 16b and
24b inputs, ctrl_chan_sel is used to select which channel is used as
a source for vertical ancillary data.
