The mmgr alloc code returns a different type than hmm, due to
some abstraction layer.
Change the driver to use just one type to represent the
hmm memory.

Most of this series are working at the memory management abstraction.
The last patch contain an important bug fix: the logic which configures
the hardware pipelines add some "delay frames" that are NULL, causing
the driver to crash when userspace selects a resolution different
than the sensor
This device driver is not MC-centric. So, remove the wrong
caps from it.

stage->args->delay_frames array could point to NULL frames.
What's weird is that we didn't notice this behavior with the
Intel Aero Yocto code.
Handle it, while adding a notice at the code, as this could
be due to some broken pipeline setup.

The frame allocation logic happens differently for userptr
or normal mmap. On a quick look, this sounded to be unbalanced,
but the logic should actually work for both cases.

There's a warning message about an unused code. The code that
were using it were commented out, due to a problem causing the
firmware load to fail on the machines we're using for testing.
Change the place where we're commenting the code out, in order
to avoid the warning.

Move the attrs handling into hmm, simplifying even further
