When cleaning up other drm config dependencies, it is too easy to create
larger problems. Instead, mark CONFIG_FB as a "depends":

The hang_limit is the threshold after which the kernel no longer
attempts to schedule a job. Its documentation stated the opposite due to
a typo. Correct the wording to indicate the actual purpose of the field.

When we want to decouble resource management from buffer management we need to
be able to handle resources separately.

Add a resource pointer and rename bo->mem so that all code needs to
change to access the pointer instead.

No functional change.

Forgetting to putting operation will result in reference leak here.
