Subject: [PATCH 2/2] thermal: core: Move initialization after core initcall

The generic netlink is initialized at subsys_initcall, so far after
the thermal init routine and the thermal generic netlink family
initialization.

On ŝome platforms, that leads to a memory corruption.

The fix was sent to netdev@ to move the genetlink framework
initialization at core_initcall.

Move the thermal core initialization to postcore level which is very
close to core level.
