Adding compatible string in TSENS dt-bindings, device node for TSENS controller and 
critical interrupt support, Thermal zone, cooling maps support and changing Hysteresis 
value for critical trip point, adding cooling-cells property.

Changes:
1) Adding sensors according to sensor index rules under thermal-zones.
2) Changing Hysteresis, as it is not needed for critical trip point, when it reaches 
   critical threshold system will go for shutdown.
3) Adding cooling-cells property under cpus node.

Dependencies:

Please add tags from previous versions, like my 'Reviewed-by' from v2,
unless a patch underwent major changes.

Please also add a change log for v > 1, even if it just says 'no changes'
for some patches in the series.

This patch doesn't change any hysteresis values, it adds them. As
commented on v2, the sentence about the hysteresis doesn't add any
value IMO, just remove it, or at least explain in a reply why you
think it is valuable.

The node name should use dashes as separator, not underscores, i.e. it
should be 'cpu-crit'. Applicable to all critical trip points.
