This patch adds the thermal needed main information for rk3228 SoCS.
Basically has the following content:
1) TSADC controller:
Add the needed attributes for rk3036 TSADC controller.
Especially for the TSHUT, in some cases if we are unable to shut it down
in orderly fashion (says: kernel is stuck holding a lock or similar), then
hardware TSHUT will reset it.
If the temperature is over 95C over a period of time the thermal shutdown
of the tsadc is invoked with can either reset the entire chip via the CRU,
or notify the PMIC via a GPIO. This should be set in the specific board.
2) Thermal zones:
Add the needed device mode for thermal generic framework.

The compatible string "simple-bus" is well defined in ePAPR, while
I see no documentation for the "arm,amba-bus" arnywhere in ePAPR or
Documentation/devicetree/.
DT is also used by other projects than Linux kernel. It is not a
good idea to rely on such an unofficial binding.
This commit
- replaces "arm,amba-bus" with "simple-bus"
- drops "arm,amba-bus" where it is used along with "simple-bus"
