UPSTREAM: PM / devfreq: rk3399_dmc: Remove explictly regulator_put call in .remove

Current code uses devm_regulator_get() in .probe so a regulator_put() will
be automatically called when unload the module. Remove the explictly
regulator_put() call and then we can also remove rk3399_dmcfreq_remove().
