pwm: lpss: drop redundant runtime PM handles

We no longer need empty runtime PM handles for PCI devices after
commits [1] and [2]. Drop them and let PCI core take care of power
state transitions.

[1] c5eb1190074c ("PCI / PM: Allow runtime PM without callback functions")
[2] fa885b06ec7e ("PCI/PM: Allow runtime PM with no PM callbacks at all")
