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.
