From: Jyri Sarha <jsa...@ti.com>
Remove all pm_runtime gets and puts, and dummy pm_ops, from the
pwm-tipwmss driver as there is no direct hardware access. The runtime PM
needs to be enabled, so that the runtime PM framework takes care of
enabling/disabling of PWMSS clock when submodules of PWMSS (ECAP or
EHRPWM) call pm_runtime APIs. With this change PWMSS clock goes to
idle when none of the submodules are in use.
