aspeed: Add support for the sonorapass-bmc board 

Sonora Pass is a 2 socket x86 motherboard designed by Facebook
and supported by OpenBMC.  Strapping configuration was obtained
from hardware and i2c configuration is based on dts found at:

1633c87b8b/arch/arm/boot/dts/aspeed-bmc-facebook-sonorapass.dts

Booted a test image of http://github.com/facebook/openbmc to login
prompt.
