[LinuxBIOS] patch for cpu in epia-m

[Anton Borisov]

Those who will test EPIA-M systems  - please add this string to cpu_table[] in file
    src/cpu/via/model_centaur/model_centaur_init.c

{ X86_VENDOR_CENTAUR, 0x0695 },         // VIA C3 Nehemiah

This will resolve problem with "Unknown CPU" and apparently will let you boot.
