[PATCH v1 3/6] pwm: tegra: Use devm function for pm_runtime_enable()

This simplifies the error paths as pwm_runtime_disable() is called
automatatically by the driver core.

Note that pwm_runtime_disable() is the right function to undo
pm_runtime_enable(); pm_runtime_force_suspend() "should only be used
during system-wide PM transitions to sleep states".
