[PATCH 1/2] ARM: dts: rockchip: update the thermal management on rk3288

[Heiko Stübner]

From: Caesar Wang <wxt at rock-chips.com>

In some cases the machine radiating is very poor,sometime the temperature
is rising very quickly on heavy loading.So we need have more frequent
polling and better granularity.
