thermal: rockchip: add virtual tsadc support for rk3126

Browse Source 
rk previous SOCs such as rk3126 have no tsadc module, so a virtual tsadc is
implemented to control the thermal problem.

the virtual tsadc is designed on considering 2 factors, one is heating
modules' heating time and the working frequences, the other one is current
leval monitored by coulometer.

Rk virtual thermal driver provides virtual temperature support for
SOCs without tsadc module. It supports one critical trip point.
