Merge patch series "Drop runtime PM support for Baytrail and Lynxpoint pinctrl" 

Raag Jadav <raag.jadav@intel.com> says:

This series removes runtime PM support for the devices that are not
explicitly attached to acpi_lpss_pm_domain as it is dead code anyway.

This has no functional impact and helps reduce their code and memory
footprint.

bloat-o-meter:
==============

Baytrail:
add/remove: 2/4 grow/shrink: 0/3 up/down: 49/-103 (-54)
Total: Before=16104, After=16050, chg -0.34%

Lynxpoint:
add/remove: 7/10 grow/shrink: 1/3 up/down: 152/-223 (-71)
Total: Before=7506, After=7435, chg -0.95%
