simple test of mapping many system memory to gpu.
before
[ RUN ] KFDMemoryTest.MMap
[ ] Using ISA for GFXIP 9.0
[ ] successfully register/map 32GB system memory to gpu
[ OK ] KFDMemoryTest.MMap (36932 ms)
after
[ RUN ] KFDMemoryTest.MMap
[ ] Using ISA for GFXIP 9.0
[ ] successfully register/map 32GB system memory to gpu
[ OK ] KFDMemoryTest.MMap (11441 ms)
So there is 11s VS 36s improvement.
Looks like we can do something similar with vm_area too.

Compare with gpu_mem_count instead of deprecated NUM_OF_SUPPORTED_GPUS
to prevent overflows in case no dGPUs are present.

There were two doorbells, one embedded in another, which are very confusing.
Change the member variable name to mapping to differentiate them. Also,
rename doorbells_mutex to just mutext for brevity.

If opening drm render device fails (usually when the user is not a member
of video group), fmm_init_process_apertures() still returns success,
resulting in weird segfault in a later stage.

Avoid warnings of the type
error: 'strncpy' specified bound 64 equals destination size
With the destination being 0-initialized, subtracting 1 from the
destination buffer size will ensure that the destination will be a
0-terminated string, even when it's truncated.

__fmm_release actually fails to find the object if address is not
pagesize aligned. And the caller did not notice this as __fmm_release
has no err code return.
So to fix this, move the object lookup in caller, and use vm-object
instead. Also fmm_release will pass up the error code.
