[coreboot] [PATCH] resource maps

[Myles Watson]

I think there's too much duplication in the resource map code.
resourcemaps.diff tries to address it by:

Creating clear_resource_map() for k8 and fam10.  This sets all the
routing registers to a known state.
Calling clear_resource_map() and then only setting the specific
registers that are non-zero in board-specific code.
Adding util.c for fam10, so that it can be customized for fam10.

I didn't update all of the resourcemap.c files, yet.  I wanted to see
what the reaction would be.

sublinks.diff marks that bit as not reserved for all fam10 boards, so
that it can be cleared.
