Subject: [PATCH 4.14 154/205] thermal: bcm2835: enable hwmon explicitly

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit d56c19d07e0bc3ceff366a49b7d7a2440c967b1b ]

By defaul of-based thermal driver do not enable hwmon.
This patch does this explicitly, so that the temperature can be read
through the common hwmon sysfs.
