In current thermal framework, it support to set trip points for the thermal
zones, but this trip point is handled by SW, doesn't have callbacks to program
the hardware.
There had patches:
[PATCH 12/16] thermal: thermal: Add support for hardware-tracked trip points,
http://lists.infradead.org/pipermail/linux-mediatek/2015-May/000866.html,
which can support to program hardware to set trip points, but it seems this
series didn't be taken.
So I add this hw-trip-points sub-node for soctherm.
