drm/i915: Enforce max hdisplay/hblank_start limits on HSW/BDW FDI
The PCH transcoder registers are only 12 bits wide for the hdisplay
and hblank_start values. On HSW/BDW the CPU side registers are 13
bits wide. intel_mode_valid() only checks against the higher limit
(since we don't know where the mode is to be used), so an extra
check is required against the FDI limits.
