Add documentation for the newly added DTS support in the shtc1 driver.
To align with the drivers logic to have high precision by default
a boolean sensirion,low_precision is used to switch to low precision.

Did Jean agree to maintain this file ?

I thought its OK to set the maintainer from the list shown with
get_maintainer.pl here. I don't mind take care of this file - there will be small changes only in case the dt-schema change and requires updates.

I put me here, if that is acceptable.

recommended

It might make sense to mention that the default is expected to be high precision
if not specified.
