[coreboot] missing read_resources for CK804

[Joseph Smith]

Hello,
Working on a new CK804 board and I have it almost booting but it seems the
resource allocator does not like / or want to enumerate the CK804. It seems
to be working fine for K8 and SuperIO but not the Southbridge. I just get a
"missing read_resources" on all CK804 devices. This is my first AMD board
so any help/direction/clues/hints would be much appreciated. Attached is
the bootlog.
