Thermal: do thermal zone update after a cooling device registered

[ Upstream commit 4511f7166a2deb5f7a578cf87fd2fe1ae83527e3 ]

When a new cooling device is registered, we need to update the
thermal zone to set the new registered cooling device to a proper
state.

This fixes a problem that the system is cool, while the fan devices
are left running on full speed after boot, if fan device is registered
after thermal zone device.

Here is the history of why current patch looks like this:
