Current command to run cloud-hypervisor binary has
wrong --rng argument in the README file.
This commit fixes all the references of --rng argument
by removing the --rng option to use default.

This updated tree now includes a fix for virtio-net regression that was
present in 5.14:

virtio-net: fix for skb_over_panic inside big mode
commit 126285651b7f ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net")
accidentally reverted the effect of
commit 1a8024239da ("virtio-net: fix for skb_over_panic inside big mode")
on drivers/net/virtio_net.c
As a result, users of crosvm (which is using large packet mode)
are experiencing crashes with 5.14-rc1 and above that do not
occur with 5.13.

Current `Getting Started` section only contains steps for the x86_64
platform, as we have a documentation doing the same thing for AArch64,
we can point users to the correct documentation.
Also, this commit modifies the `docs/arm64.md` to fit the documentation
style within the project.

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 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.

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.

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=".
