[coreboot] CBFS via/epia-m700 and via/pc2500e problems?

[Carl-Daniel Hailfinger]

via/epia-m700 and via/pc2500e do not have fallback/coreboot_ram in the
abuild images. Instead they have image/coreboot_ram which will probably
cause cbfs code to die.
If my suspicion is correct, those targets need fixups similar to r4589.
