thermal: core: Initialize thermal zones before registering them

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2101915

[ Upstream commit 662f920f7e390db5d1a6792a2b0ffa59b6c962fc ]

Since user space can start interacting with a new thermal zone as soon
as device_register() called by thermal_zone_device_register_with_trips()
returns, it is better to initialize the thermal zone before calling
device_register() on it.

Fixes: d0df264fbd ("thermal/core: Remove pointless thermal_zone_device_reset() function")
