Getting Started Guide: update to reflect the new boot flow

Browse Source 
The boot process has changed a bit and the ACRN hypervisor is now
directly loaded by the platform EFI firmware. This commit reflects
those changes and also reference a newer version of Clearlinux that
includes the ACRN hypervisor that has these changes in.

ACRN requires Clear Linux version 22140 or newer. The instructions below
have been validated with version 22140 and need some adjustment to work
with newer versions. You will see a note when the instruction needs to be
adjusted.
1. Follow this `Clear Linux installation guide
#. Download the compressed Clear installer image from
https://download.clearlinux.org/releases/22140/clear/clear-22140-installer.img.xz

folder to get Clear Linux version 21260.
as a starting point for installing Clear Linux onto your NUC. Follow the recommended
options for choosing an **Automatic** installation type, and using the NUC's
storage as the target device for installation (overwriting the existing data
and creating three partitions on the NUC's SSD drive).
2. At the "Choose Installation Type" screen, choose the "< Automatic >"
option. This will install the minimum Clear Linux components.
#. After installation is complete, boot into Clear Linux, login as
**root**, and set a password.
3. At the "Choose target device for installation" screen, select your
NUC's storage device to delete all existing content and create
partitions automatically. The installer will
create three partitions as shown in :numref:`CL-partitions`
for the recommended 120GB SSD drive.

#. Configure the EFI firmware to boot the ACRN hypervisor by default
The ACRN hypervisor (``acrn.efi``) is an EFI executable
loaded directly by the platform EFI firmware. It then in turns loads the
Service OS bootloader. Use the ``efibootmgr`` utility to configure the EFI
firmware and add a new entry that loads the ACRN hypervisor.
.. code-block:: none
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda1 -p 1 -L ACRN

.. note::
Be aware that a Clearlinux update that includes a kernel upgrade will
reset this. A Clearlinux update could happen automatically (if you have
not disabled it as described above), if you later install a new
bundle to your system or simply if you decide to trigger an update
manually. Whenever that happens, double-check the platform boot order
using ``efibootmgr -v`` and modify it if needed.
#. Create a boot entry for the ACRN Service OS by copying a provided ``acrn.conf``
and editing it to account for the kernel versions noted in a previous step.

If you're following
the instructions above, the partition (``root=/dev/sda3``) and image
locations used in the ``arcn.conf`` file will match.
You will need to edit this file to adjust the kernel version (``linux`` section)
and also insert the ``PARTUUID`` of your ``/dev/sda3`` partition
(``root=PARTUUID=<><UUID of rootfs partition>``) in the ``options`` section.
.. note::
Please make sure that the kernel version and root filesystem image (``clear-<version>-kvm.img``)
match your set-up.
Use ``blkid`` to find out what your ``/dev/sda3`` ``PARTUUID`` value is.
