Review comment:
Zephyr should have no real impact on the memory pre-allocated here as
it's just a block in flash, this is deeply worrying as the allocator is
configured here:
https://github.com/apache/tvm/blob/7d831e1dd34d441e9217096d0baf78e6f97c77d9/apps/microtvm/zephyr_cmsisnn/src/main.c#L62
Thus the allocator itself should never go over if it's performing properly,
something is very weird here but I agree we should investigate further when
we've integrated USMP fully.
