Julius Werner 6911219ccc edid: Add helper function to calculate bits-per-pixel dependent values 
Coreboot and most payloads support three basic pixel widths for the
framebuffer. It assumes 32 by default, but several chipsets need to
override that value with whatever else they're supporting. Our struct
edid contains multiple convenience values that are directly derived from
this (and other properties), so changing the bits per pixel always
requires recalculating all those dependents in the chipset code. This
patch provides a small convenience wrapper that can be used to
consistently update the whole struct edid with a new pixel width
instead, so we no longer need to duplicate those calculations
everywhere.

BUG=None
TEST=Booted Oak in all three pixel widths (which it conveniently all
supports), confirmed that images looked good.
