Previously the CONFIG_PM_SLEEP and !CONFIG_PM_SLEEP device_init_wakeup()
implementations differed in confusing ways:
- The PM_SLEEP version checked for a NULL device pointer and returned
-EINVAL, while the !PM_SLEEP version did not and would simply
dereference a NULL pointer.
- When called with "false", the !PM_SLEEP version cleared "capable" and
"enable" in the opposite order of the PM_SLEEP version. That was
harmless because for !PM_SLEEP they're simple assignments, but it's
unnecessary confusion.
Use a simplified version of the PM_SLEEP implementation for both cases.
