drm/i915: fix lane bandwidth capping for DP 1.2 sinks
DP 1.2 compatible displays may report a 5.4Gbps maximum bandwidth which
the driver will treat as an invalid value and use 1.62Gbps instead. Fix
this by capping to 2.7Gbps for sinks reporting a 5.4Gbps max bw.
Also add a warning for reserved values.
