[PATCH] thermal: rockchip: enable hwmon

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@xxxxxxxx>

By default of-based thermal driver do not have hwmon entries registered.

Do this explicitly so users can use standard hwmon interfaces and tools
to read the temperature.

This is based on similar changes for bcm2835_thermal in commit
d56c19d07e0b ("thermal: bcm2835: enable hwmon explicitly").
