add common fan control asic callbacks
Adds 4 callbacks for managing fan state/speed * fan_ctrl_set_mode - manages fan control mode (nonzero == manual) * fan_ctrl_get_mode - queries fan control mode * set_fan_speed_percent - manages fan speed as percentage value * get_fan_speed_percent - queries fan speed as percentage value Signed-off-by: Oleg Chernovskiy <algonkvel@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
