Subject: [PATCH] thermal/drivers/core: Remove the module Kconfig's option

The module support for the thermal subsystem does have a little sense:
 - some subsystems relying on it are not modules, thus forcing the
   framework to be compiled in
 - it is compiled in for almost every configs, the remaining ones
   are a few platforms where I don't see why we can not switch the thermal
   to 'y'. The drivers can stay in tristate.
 - platforms need the thermal to be ready as soon as possible at boot time
   in order to mitigate

Usually the subsystems framework are compiled-in and the plugs are as module.

Remove the module option. The removal of the module related dead code will
come after this patch gets in or is acked.
