This concerns both `nordic,owned-memory` and `nordic,owned-partitions`.
Introduce a property named `nordic,access`, which is meant to replace
the `owner-id` and `perm-*` properties. It allows for describing how
multiple domains should access a single memory region, possibly with
different permissions per owner, but without having to create more than
one DT node for this purpose.
This change is also motivated by updated memory protection requirements
on the nRF54H20, which mandate that a given memory region must only be
reserved by one domain, even if multiple domains can have access to it.
This restriction is now described in the binding itself.

Add a set of bindings that will be used in the nRF54H20 SoC definition.
Extend the existing GPIOTE binding with properties needed for this SoC.
Also do a tiny clean-up in the bindings added recently for nRF54L15
(HFXO and LFXO).

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

The reserved memory mechanism (sections and regions definition) has been
entirely replaced, greatly extended and made it better by the work done
on the zephyr,memory-region compatible.
Since there is are no actual users, we can remove it.

Since the introduction of the `zephyr,memory-region` compatible
to create new memory region, drivers can now use the newly defined
region in the DT by using the macro LINKER_DT_NODE_REGION_NAME()
on the node_id to retrieve the region name and possibly allocated data
or variables in that region (or for whatever other use).
This is assuming though that the driver knows in advance the node_id to
reference.
A better approach is to add a new generic 'memory-region' property
that can be used by any driver to reference a region by using a phandle,
so that the driver can use that to retrieve the memory-region of interest.

Introduce a set of header files to be able to define and declare
sections and regions in the linker script. Introduce also DT helpers to
retrieve data back.
