Subject: [PATCH 1/2] dt-bindings: thermal: correct thermal zone node name limit

Linux kernel uses thermal zone node name during registering thermal
zones and has a hard-coded limit of 20 characters, including terminating
NUL byte.  The bindings expect node names to finish with '-thermal'
which is eight bytes long, thus we have only 11 characters for the reset
of the node name, not 12.

Reported-by: Rob Herring <robh@...nel.org>
Closes: https://lore.kernel.org/all/CAL_JsqKogbT_4DPd1n94xqeHaU_J8ve5K09WOyVsRX3jxxUW3w@mail.gmail.com/
Fixes: 1202a442a31f ("dt-bindings: thermal: Add yaml bindings for thermal zones")
