It is? The DP 1.1a text for lane count is "For Rev.1.1, only the
following three values are supported. All other values are reserved."

Yeah, if you look at the MAX_LINK_RATE field, we assume that it has a
useful value. I'll bet they were thinking of letting the spec support
things like alternate clock rates or 3 lanes or something, and the 1.1
version just tied things down to allow only sensible values there.

How about we just always use the DPCD value?

Looks good.
