We can update wlcore to use PM runtime by adding functions for
wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing
calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls
to pm_runtime_get_sync() and pm_runtime_put().
Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume()
functions are based on simplified versions of wl1271_ps_elp_sleep() and
wl1271_ps_elp_wakeup(). We don't want to use the old functions as we
can now take advantage of the runtime PM usage count. And we don't need
the old elp_work at all. And we can also remove WL1271_FLAG_ELP_REQUESTED
that is no longer needed.
Then eventually should allow us to use pm_runtime_autosuspend in
further patches instead of the custom handling. And we should be able
to start using Linux generic wakeirqs for the padconf interrupt.
