Jason A. Donenfeld c7b28f52f4 drm/i915/display: Re-add check for low voltage sku for max dp source rate 
This reverts commit 73867c8709 ("drm/i915/display: Remove check for
low voltage sku for max dp source rate"), which, on an i7-11850H iGPU
with a Thinkpad X1 Extreme Gen 4, attached to a LG LP160UQ1-SPB1
embedded panel, causes wild flickering glitching technicolor
pyrotechnics on resumption from suspend. The display shows strobing
colors in an utter disaster explosion of pantone, as though bombs were
dropped on the leprechauns at the base of the rainbow.

Rebooting the machine fixes the issue, presumably because the display is
initialized by firmware rather than by i915. Otherwise, the GPU appears
to work fine.

Bisection traced it back to this commit, which makes sense given the
issues.

Note: This re-opens, and puts back to the drawing board,
https://gitlab.freedesktop.org/drm/intel/-/issues/5272 which was fixed
by the regressing commit.
