Subject: [PATCH] busybox: add create-edid-cpio script

This script simply creates /flash/edid.cpio with the contents from
.config/firmware/edid

Compared to the x86 specific getedid script this works on all platforms
as it doesn't contain any platform specific code. Eventually getedid
should be refactored make use of this helper script, too.
