Subject: [PATCH v5 0/2] Enable Service layer driver for Agilex5

This patch series introduces support for the Agilex5 service layer driver
(SVC) in the Linux kernel. The changes span across device tree bindings,
platform DTS files, and the Stratix10 SVC firmware driver.

These changes are necessary to enable firmware communication on Agilex5
SoCs via the SVC interface, similar to existing support for Stratix10 and
Agilex platforms.

Agilex5 introduces the ability for the TBU to operate in non-secure mode,
making it accessible to Linux through the IOMMU framework. This key
difference enables improved memory management in non-secure environments.
As a result, this series extends the SVC driver and device tree bindings
to support IOMMU integration for Agilex5.

Notes:
This patch series is applied on socfpga maintainer's tree
https://git.kernel.org/pub/scm/linux/kernel/git/dinguyen/linux.git/log/?h=socfpga_dts_for_v6.19

Changes in v5:
	- Use contains enum instead of const
Changes in v4:
	- Refactor the logical check without using AllOf.
Changes in v3:
	- Remove driver changes in driver as it is fully compatible
	- Add iommu entry and rewrite the git commit message to describe
	  why the changes is required.
Changes in v2:
	- Add driver changes for Agilex5-svc compatible
