[coreboot] seaBIOS config options "for emulators"

[Joe Julian]

Hello Kevin,

You suggested, on the coreboot IRC channel, that I enable smbios in 
seabios to solve the missing mptable and RSDP problem. The reason those 
are turned off is because the comments for CONFIG_PIRTABLE, 
CONFIG_MPTABLE, COMFIG_SMBIOS, and CONFIG_ACPI all state, "for 
emulators". Since this is a bare metal install, wouldn't it be correct 
to have those options disabled since we need the real data rather than 
simulated data?

Thanks,
Joe
