Subject: [PATCH v17 4/5] ARM: dts: add main Thermal info to rk3288

This patch is depend on rk3288-thermal.dtsi,or
it will compile error.

If for some reason we are unable to shut it down
in orderly fashion (kernel is stuck holding a lock or
similar), then hardware TSHUT will reset it.

If the temperature over a period of time High,over 105C
the resulting TSHUT gave CRU module,let it reset
the entire chip,or via GPIO give PMIC.
