99e72be169 unit tests: Fix unit tests and docs for AArch64
Currently, not every feature of the cloud-hypervisor is enabled
on AArch64, which means that on AArch64 machines, the
`run_unit_tests.sh` needs to be tailored and some unit test cases
should be run on x86_64 only.

Also this commit fixes the typo and unifies `Arm64` and `AArch64`
in the AArch64 document.

b8e1cf2d4e vm-allocator: Add new function to free 32 bits MMIO address space
The allocator already had functions to allocate and free both IO and 64
bits MMIO address spaces, but it only had an allocating function for 32
bits MMIO address space.

With this new function, it will be now possible to remove cleanly some
ranges from the 32 bits MMIO address space.

0ff074d2b8 vm-allocator: Fix potential allocation errors
There is one corner case which was not properly handled by the current
code from our AddressAllocator. If both the address start (from the
next range) and the requested region size are already aligned on the
same value as "alignment", when doing the substract of the requested
size + alignment, the returned address is already aligned. The problem
is that we might end up overlapping with an existing range since the
check between the available delta and the requested size does not take
into account a full extra alignment.

By substracting the requested size + alignment - 1 from the address
start of the next range, we ensure this kind of corner case would not
happen since the address won't be naturally aligned and after some
adjustment from the function align_address(), the correct start address
will be returned.

f98a69f42e vm-allocator: Introduce an MMIO hole address allocator
With this new AddressAllocator as part of the SystemAllocator, the
VMM can now decide with finer granularity where to place memory.

By allocating the RAM and the hole into the MMIO address space, we
ensure that no memory will be allocated by accident where the RAM or
where the hole is.
And by creating the new MMIO hole address space, we create a subset
of the entire MMIO address space where we can place 32 bits BARs for
example.

a761b820c7 vm-allocator: Fix the aligned address check
The requested address for a range can be the base of the entire
address space, this is a valid use case.

In particular, when creating an MMIO address space of 0-64GiB, we
might want to create a range of 0-1GiB if the RAM of our VM is 1G.

709148803e vm-allocator: Fix free range allocation
This patch fixes the function first_available_range() responsible
for finding the first range that could fit the requested size.

The algorithm was working, that is allocating ranges from the end
of the address space because we created an empty region right at the
end. But the problem is, the VMM might request for some specific
allocations at fixed address to allocate the RAM for example. In this
case, the RAM range could be 0-1GiB, which means with the previous
algorithm, the new available range would have been found right after
1GiB.

This is not the intended behavior, and that's why the algorithm has
been fixed by this patch, making sure to walk down existing ranges
starting from the end.
