PD#SWPL-141014 Problem: txhd2 need to add media related thermal control Solution: 1. add media cooling device. media module should call media_cooling_register to register the cooling device. and usually configure maxstate of the cooling device. 2. reconstruct cpucore cooling device. Verify: txhd2 Change-Id: I0576e0d91a3062b60f877a4e8577e4fe84e5f53b Signed-off-by: Xingxing Wang <xingxing.wang@amlogic.com>
