thermal: core: Simplify unregistration of governors

Thermal governors are only unregistered in the thermal_init() error
path and they actually are only deleted from thermal_governor_list.

Put the entire code needed to do that to thermal_unregister_governors()
and rearrange thermal_init() to call that function also when
thermal_register_governors() returns an error.

This allows thermal_unregister_governor() to be dropped
and thermal_register_governor() that is only called by
thermal_register_governors() can be made static __init, so the
headers of these two functions can be dropped from thermal_core.h.

No intentional functional impact.
