Dear Daniel,

We introduce the new thermal hardware design called lvts in the new
project. The new project will desgin with lvts will enable the
CONFIG_MTK_SOC_THERMAL_LVTS to build lvts driver[1].
The old project will use CONFIG_MTK_THERMAL to build soc_temp.c.

The new design use lvts device to access thermal sensors in the soc.
The original design access thermal sensors by auxadc.
