Driver core: Fix cleanup when failing device_add().
- Don't call cleanup_device_parent() if we didn't call setup_parent().
- dev->kobj.parent may be NULL when cleanup_device_parent() is called,
so we need to handle glue_dir == NULL in cleanup_glue_dir().

Since device_pm_remove(dev) calls dpm_sysfs_remove(dev), it's
incorrect to call the latter after the former in the device_add()
error path.

This patch (as1041) fixes a bug introduced by the
acquire-all-device-semaphores reversion. The error pathway of
dpm_suspend() fails to reacquire a mutex it should be holding.

- If the allocation of ->priv fails, the reference on the bus
must be dropped.
- If adding the kobject fails, kobject_put must be called to
clean things up.

This reverts commit 109f0e93b6.
The original patch breaks BIOS updates on all Dell machines. The path to
the firmware file for the dell_rbu driver changes, which breaks all of
the userspace tools which rely on it.
Note that this patch re-introduces a problem with i2c name collision
that was previously fixed by this patch.

Driver core: Remove unneeded get_{device,driver}() calls.
Code trying to add/remove attributes must hold a reference to
the device resp. driver anyway, so let's remove those reference
count games.

Move the declaration of device_pm_schedule_removal() to device.h
and make it exported, as it will be used directly by some drivers
for unregistering device objects during suspend/resume cycles in a
safe way.

When trying to debug a suspend failure I started implementing
PM_TRACE for powerpc. I then noticed that I'm debugging a suspend
failure and so PM_TRACE isn't useful at all, but thought that
nonetheless this could be useful in the future.
Basically, to support PM_TRACE, you add a Kconfig option that
selects PM_TRACE and provides the infrastructure as per the
help text of PM_TRACE.

The driver core, and some other parts of the kernel just want to find a
device based on a name for a specific bus. Give them a simple wrapper
to prevent them from having to always roll their own.
This will be used in the PPC patch later in this series.
