PM: Do not acquire device semaphores upfront during suspend
Remove the code that acquires all device semaphores from the suspend
code path as it causes multiple problems to appear (most notably,
http://bugzilla.kernel.org/show_bug.cgi?id=10030) and revert the
change introduced by commit 4145ed6dc597a9bea5f6ae8c574653b2de10620f
depending on the code being removed.
Remove pm_sleep_lock()/pm_sleep_unlock() from device_add() to avoid
the issue reported at http://bugzilla.kernel.org/show_bug.cgi?id=9874.
It should fix the regreesions reported at:
http://bugzilla.kernel.org/show_bug.cgi?id=9874
http://bugzilla.kernel.org/show_bug.cgi?id=10030
