link/graphics: Add support for EDID

This code is taken from an EDID reader written at Red Hat.

The key function is
int decode_edid(unsigned char *edid, int size, struct edid *out)

Which takes a pointer to an EDID blob, and a size, and decodes it into
a machine-independent format in out, which may be used for driving
chipsets. The EDID blob might come for IO, or a compiled-in EDID
BLOB, or CBFS.

Also included are the changes needed to use the EDID code on Link.
