amd/bettong: Enable fan control

1. Use enable_imc_thermal_zone to enable fan control.
    2. The ACPI method ITZE works on Ubuntu 14.04 and Windows 7
    but does not work on Windows 8, so I didn't use it.
    After this issue is fixed, I'll add ACPI_ENABLE_THERMAL_ZONE
    in bettong/Kconfig.
    3. Fan control works on Bettong. I used "APU Validation Toolkit"
    to test on Windows 8. This tool can put load to APU. The fan's
    behaviour is just like bettong/fchec.c defined. When the temperature
    is 40 Celsius, the fan start to run.
