add tyan s8226: add a new mainboard

our code supports tyan s8226 now, which has two cpus on the board
the cpu socket is C32. The details of tyan s8226 is:
http://www.tyan.com/product_SKU_spec.aspx?ProductType=MB&pid=679&SKU=600000190
the test result of this mainboard is:
1) boot Ubunbu 11.10, kernel 3.0.9. there is no err and warnings in
dmesg.
2) boot windows7 x64 successfully.
3) use fwts to test the bios, there are 268 pass and 14 failed
4) pcie and usb slots are ok.
5) all network interfaces are ok.
