[PATCH 4/6] drm/bridge: aux: allow interlaced and YCbCr 420 output

[Dmitry Baryshkov]

As both aux bridges are merely passthrough bridges, mark them as
supporting interlaced and YCbCr 420 data. Other bridges in the chain
still might limit interlaced and YCbCr 420 data support on the
corresponding connector.
