[PATCH v5 24/24] pwm: add information about polarity, duty cycle and period to debugfs

From: Heiko Stübner <heiko@sntech.de>

The pwm-states make it possible to also output the polarity, duty cycle
and period information in the debugfs pwm summary-outout.
This makes it easier to gather overview information about pwms without
needing to walk through the sysfs attributes of every pwm.
