Extend pm.h by pm_sleep_ptr and DEFINE_SIMPLE_DEV_PM_OPS(). For the moment this duplicates some parts (as can be seen in the earlier review I tried to simplify bits but given our implementation this was easier in the end). While here and cleanup the SIMPLE_DEV_PM_OPS() bits (white-space only). MFC after: 3 days Reviewed by: hselasky Differential Revision: https://reviews.freebsd.org/D37527
