Yocto Aero driver has a different default for hmm pools.
Use the definitions there.

The code for it is commented out, probably because it is
broken or uneeded for the driver to work. So, let's get
rid of it.

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.

The code there is a wrapper for hmm/ wrapper. Simplify it,
and get rid of ION-specific code.

Yet another memory abstraction layer. Getting rid of this
may be a little trickier, but let's reduce it to a minimal.

Now that we have everything in place, we can get rid of the
memory_access abstraction layer.
Now, everything related to heterogeneous memory management
(hmm) is under hmm.c & related pools.

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.

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 res
For debugging purposes, it helps to know what event
was actually received.

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.
Add an extra comment to reflect it.

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.
