The changes have dependency on merging tsens-common.c into tsens.c [1]
to merge first.

Dependencies:
[1] https://lkml.org/lkml/2020/4/29/1028

Changes in v3:
* Add cold interrupt support to tsens driver
* Update cold interrupt support in yaml

TSENS IP v2.6+ adds cold interrupt support. It triggers set
interrupt when aggregated minimum temperature of all TSENS falls
below cold preset threshold, 5 degree Celsius and triggers
reset interrupt when aggregated minimum temperature of all TSENS
crosses above reset threshold, 10 degree Celsius. These threshold
values could change in boot firmware code. Add support for this
interrupt in the driver.

It adds another virtual sensor to the of-thermal along with all
individual TSENS. This cold sensor only gives cold state value of
1 or 0 for successful temperature read. A state value of 1 indicates
minimum one TSENS is in cold temperature condition and state value
of 0 indicates all TSENS are out of cold temperature condition.
