[PATCH] fbdev: Resurrect hooks to get EDID from firmware
For the i386, code is already present in video.S that gets the EDID from the
video BIOS. Make this visible so drivers can also use this data as fallback
when i2c does not work.
To ensure that the EDID block is returned for the primary graphics adapter
only, by check if the IORESOURCE_ROM_SHADOW flag is set.
