Make the imx_thermal driver use the .should_bind() thermal zone callback
to provide the thermal core with the information on whether or not to
bind the given cooling device to the given trip point in the given
thermal zone.  If it returns 'true', the thermal core will bind the
cooling device to the trip and the corresponding unbinding will be
taken care of automatically by the core on the removal of the involved
thermal zone or cooling device.

In the imx_thermal case, it only needs to return 'true' for the passive
trip point and it will match any cooling device passed to it, in
analogy with the old-style imx_bind() callback function.
