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 (thus 10 for the pattern after leading fixed character).
