LinuxKPI: restore several hard coded return values for the CONFIG_PM caseHEADmain

drm-kmod sets CONFIG_PM (unclear if for other parts) but LinuxKPI
has no understanding of a dev->power implementation for pm_runtime.h.

The return values based on !CONFIG_PM thus cause problems to drm-kmod.
Return the previous values under CONFIG_PM but leave the TODO logging
as the actual implementation is missing and return values may not be
universally correct (beyond the known drm-kmod use cases).

The following functions having a return value but none sepcific for
CONFIG_PM as (based on drm-kmod master):
pm_runtime_resume          only caller ignores the return value
pm_runtime_set_active      two callers ignore the return value
pm_runtime_put_autosuspend all callers seem to ignore the return value
pm_runtime_autosuspend     2/3 callers ignore the return value;
                           3rd is #ifdef __linux__
pm_runtime_suspended       3/4 callers ... do check the return value
                           but the logic expects the false, which also
                           matches the previous value.
