Now that the debugging macros are cleaned up, just rely on the dynamic
debug code in the kernel to do the debug messages for the driver.
This lets debugging be enabled without having to rebuild the driver, an
important thing for users that can not do it.

Now that no USB atm driver is relying on the CONFIG_USB_DEBUG option
(well, really the DEBUG option, thanks to some Makefile fun), remove it
from the Makefile.
Also remove two last vestiges of DEBUG in the usbatm.c driver, moving
one to VERBOSE_DEBUG, which no one ever really cares about, and the
other to use the dynamic debug subsystem.

Move the atm_dbg() call to use the dynamic debug subsystem, and not rely
on CONFIG_USB_DEBUG for if things should be printed out or not.
This also means the drivers do not have to be rebuilt to get debugging

rebuild their kernels.

"This contains two patches, both of which aren't fixes per-se but I
think it'd be better to fast-track them.
One removes bcache_subsys_id which was added without proper review

unconditionally disabled, so this was never exposed to userland. The
cgroup subsys_id is removed. Kent will remove the affected (disabled)
code through bcache branch.
The other simplifies task_group_path_from_hierarchy(). The function
doesn't currently have in-kernel users but there are external code and
development going on dependent on the function and making the function
available for 3.11 would make things go smoother"
