cpufreq: integrator: fix integrator_cpufreq_remove return type
When building this driver as a module, we get a helpful warning
about the return type:
drivers/cpufreq/integrator-cpufreq.c:232:2: warning: initialization from incompatible pointer type
.remove = __exit_p(integrator_cpufreq_remove),
If the remove callback returns void, the caller gets an undefined
value as it expects an integer to be returned. This fixes the
problem by passing down the value from cpufreq_unregister_driver.
