[PATCH v3 00/12] Static shared memory followup v2 - pt1

[Luca Fancellu <luca.fancellu@arm.com>]

This serie is a partial rework of this other serie:
https://patchwork.kernel.org/project/xen-devel/cover/20231206090623.1932275-1-Penny.Zheng@arm.com/

The original serie is addressing an issue of the static shared memory feature
that impacts the memory footprint of other component when the feature is
enabled, another issue impacts the device tree generation for the guests when
the feature is enabled and used and the last one is a missing feature that is
the option to have a static shared memory region that is not from the host
address space.

This serie is handling some comment on the original serie and it is splitting
the rework in two part, this first part is addressing the memory footprint issue
and the device tree generation, there will be a following serie addressing the
last missing feature soon.

From v2:
 - Removed merging of the /memory interval

From v1:
 - Add new patches, moved the patch related to the static memory helper.
