Moving to the latest kernel 5.14 simplifies greatly the list of patches
that we need to carry. Since virtio-iommu has been merged as part of the
5.14 release, the only remaining patches are virtio-watchdog and the EFI
reboot.

Since using the VIRTIO configuration to expose the virtual IOMMU
topology has been deprecated, the virtio-iommu implementation must be
updated.
In order to follow the latest patchset that is about to be merged in the
upstream Linux kernel, it must rely on ACPI, and in particular the newly
introduced VIOT table to expose the information about the list of PCI
devices attached to the virtual IOMMU.

The 0.3.0 release (re)supports booting stock Ubuntu images so users
should be pointed towards that.

Only use `cloud-hypervisor` when referring to the binary itself and
prefer Cloud Hypervisor when referring to the project.

The command which is mentioned in the README is wrong. We have two
cofigs one for x86_64 and another for aarh64. Previously it was a single
config. After adding the configs the read me was not modified. This
patch fixes the issue.

Now that our CI has transitioned from ClearLinux to Ubuntu images
exclusively, let's update the documentation to refer to Ubuntu images
instead of ClearLinux's ones.

Since we only keep one single version of the kernel config file in our
repository, there is no reason to keep the filename complex.

The kernel version is updated from 5.5-rc1 to 5.6-rc4, including the
updated kernel config file.
The kernel branch contains virtio-fs, virtio-iommu and virtio-mem
patches that are not upstream yet. It also contains one fix for
virtio-vsock which will be merged upstream in the next release.

Update all references to the new repository locations. Many of these will
redirect however the one used for the hypervisor-fw binary does not so
this is required to allow the builds to pass.

This commit introduces a dedicated document describing the device model
supported by cloud-hypervisor VMM.
It needs to be updated anytime a new device will be added in the future.

The firmware has been recently updated to find the EFI partition, no
matter if the disk is not the first one of the list.

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=".
