[PATCH] thermal: Hunt zero trip points thermal zones usage

[Daniel Lezcano <daniel.lezcano@linaro.org>]

Some drivers are declaring a thermal zone without any thermal trip
points.

On the other side, we are introducing the function
thermal_zone_device_register_with_trips() which provides an array of
generic thermal trip points. When all the drivers will be converted to
the generic trip points, keeping two functions will be useless.

Most of the drivers are now using
thermal_zone_device_register_with_trips() with the generic trip
points. As soon as the remaining drivers are merged, the
thermal_zone_device_register_with_trips() will be renamed to
thermal_zone_device_register().

Obviously this renaming can only happen if there are no more user of
the thermal_zone_device_register() function.

This change uses thermal_zone_device_register_with_trips() with a NULL
parameter for the trip point array instead of
thermal_zone_device_register().

No functional change intended.
