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.
