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.
