A frequent issue that arises on shutdown is the drm_mm range manager
complaining of a leak. To aide debugging those, drm can now track the
allocation callsite and print those for the leaks.

We can use the kernel's stack tracer and depot to record the allocation
site of every drm_mm user. Then on shutdown, as well as warning that
allocated nodes still reside with the drm_mm range manager, we can
display who allocated them to aide tracking down the leak.

v2: Move Kconfig around so it lies underneath the DRM options submenu.

It is controlled via I2C bus. Its interaction with other

filtering-out unsupported video modes, it exposes drm_bridge

The current default of always using the performance power state leads
to increased power consumption of mobile devices, which have a dedicated
battery power state. Switch between the performance and battery power
state automatically, dpending on the current AC power status, when the
user asked for the balanced power state.

The user can still override this logic by asking for the performance
or battery power state explicitly.
