From: Ville Syrjälä <ville.syrjala at linux.intel.com>

An attempt at making the bigjoiner state tracking both smaller and
more flexible for future needs. All we really need is a bitmask of

I also managed to fix a bunch of issues with the state copy ...
I think. It's a bit hard to know for sure since I don't have
a DSC capably  displauy so I'm just forcing the driver to spew
out DSC but obviously I can't actually see anything on the screen.

The next thing that needs fixing is the actual modset sequence
since it's still kinda terrible. Also not flexible enough for
those future needs. I'm thinking we need suck all the logic into
the encoder hooks, and let those iterate over the pipes at
approprite times. But that's for another time.

Pushed the lot here if someone wants to consume it easier:
