Added compatible string in TSENS dt-bindings, device node for TSENS controller and
critical interrupt support, Thermal zone support, cooling maps and added hysteresis
as zero as it is not needed for critical trip points.
Changes:
1) Added sensors according to sensor ID's under thermal-zones.
2) Added hysteresis as zero as it is not needed as system is supposed to shut down when critical point is reached.

I don't think it's necessary to explain the hysteresis values unless
they are really uncommon.

In the review of v1 (https://patchwork.kernel.org/project/linux-arm-msm/patch/[email protected]/)
I suggested that a hysteresis isn't needed for the critical trip
points, but this patch also also gets rid of the hysteresis values
for the passive and hot trip points, which isn't correct.

uber-nit: I still think an alphabetical order would be preferable, it
makes it easy to locate the zones, whereas the indices of the TSENS
sensor are mostly irrelevant for the order. Anyway, AFAIK there are
no clear rules or conventions regarding this, so it's ok if yo
prefer to leave it as is.
