In a lots of places in DPU driver memory is allocated by using the
kzalloc and then manually freed using kfree. However thes memory chunks
have a well-defined life cycle. They are either a part of the driver's
runtime and can be devm_kzalloc'ed or are exposed to userspace via the
DRM objects and thus can be drmm_alloc'ed. Implement corresponding
runtime resource manangement for the DPU driver.

Dependencies: [1].
