The cloud-hypervisor supports the DAX shared region for better virtio-fs
performances, but it was not updated in the documentation. This commit
takes care of this and also update the mount command since it changed
with virtio-fs v0.3.
Fixes#433

Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-blk device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".
One side effect of this new option is that we had to introduce a new
option for the disk path, simply called "path=".
