Subject: [PATCH] thermal: update header and documentation

The commit commit f991de53a8ab ("thermal: make device_register's type
argument const") changed APIs, but only when CONFIG_THERMAL enabled case.

This patch is partial from https://lkml.org/lkml/2019/5/14/631 which
tries to address the same concern,
