FrontRunner/Toucan-AF: drop unnecessary compile time CPU model selection 

The first reason for selecting the CPU model at compile time was a
multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2.
Recent tests show the pause has disappeared, someone must have fixed it.

The second reason was me not knowing how to make a single vgabios image
work with two different PCI IDs.  Many thanks to Martin Roth for educating
me!  Quote:

"The way to make coreboot use the same vbios for different video device IDs
 is through the map_oprom_vendev function. In family 14 it's in
 northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video
 bios 1002,9802 in the config and all the other device/vendor IDs for the
 family 14h processors will fall through the initial check for the video
 bios and will get remapped to use that vbios. This only works if you're
 initializing the vbios inside coreboot. I don't know if you're using
 SeaBios as a payload, but if you are you can add the vbios to cbfs as
 vgaroms/vbios.rom and the rom will always be initialized."

I'd like to add the vgabios is added as type 'optionrom' when Coreboot make
adds it, however to work with SeaBios it has to be added manually with
cbfstool and with type 'raw', or it will hang.
