After 5.11-rc4, memory hotplug alignment size is reduced to 128M for 4K
page.
It works better for memory hotplug and nvdimm plug in kata on arm.
without this patch, memory hotplug will fail for the current memory
hotplug alignment is 1G but the nvdimm size align with 128M in kata.
After port it here, we can avoid a fix in qemu side.
Note: if you change the page size to other size than 4K, memory hotplug
will has no effect.

In kernel 5.10.x on arm64 side, When CONFIG_RANDOM_BASE is enabled,
physical base address can be a negative number. It may lead to bug
when a PA is taken as a unsigned number in comparison, as PA is
calculated based on the physical base address. The bug has been fixed
latest code by commit ee7febce051945be2 in memory hotplug zone. We can
eliminate the bug in an easy way by casting the PA as a signed value in
the current code base to avoid lots of backport.

Now, cloud-hypervisor is capable to work on arm64. it's time to

as cloud-hypervisor can only use virtio-fs, a new patch should be
applied to kernel for virtiofs and some config should be removed
temporarily.
