amd/pi/hudson: Move oem_fan_control()
It was not intentional to change oem_fan_control() to non-static
with commit
23e5ba9 binarypi mainboards: Clean up IS_ENABLED fan control
Every platform except bettong had its own static version of
oem_fan_control, so remove the definition of oem_fan_control from imc.h,
and move it out of imc.c into bettong's BiosCallOuts.c.
