[PATCH v4 2/8] thermal: Provide stub for thermal_cdev_update() function

[Lukasz Majewski <l.majewski@samsung.com>]

Odroid U3 fan can work without being registered as OF cooling device
(with CONFIG_THERMAL{_OF|} disabled).
In this situation it can be controlled via PWM entry at
/sys/class/hwmon/hwmon0/pwm1.

Therefore, the thermal_cdev_update() function needs a stub
to allow clean compilation.
