drm/i915: Check timings against hardware maximums Validate that all display timings fit within the number of bits we have in the transcoder timing registers. The limits are: hsw+: 4k: vdisplay, vblank_start 8k: everything else gen3+: 4k: h/vdisplay, h/vblank_start 8k: everything else gen2: 2k: h/vdisplay, h/vblank_start 4k: everything else Also document the fact that the mode_config.max_width/height limits refer to just the max framebuffer dimensions we support. Which may be larger than the max hdisplay/vdisplay.
