Subject: [PATCH v4 1/2] dt-bindings: fpga: stratix10: add support for Agilex5

Agilex5 introduces changes in how reserved memory is mapped and accessed
compared to previous SoC generations. Agilex5 compatible allows stratix10-
FPGA manager driver to handle these changes.

Fallback is added for driver probe and init that rely on matching of table
and DT node.

Changes in v4:
	- Remove redundant "items - enum" as suggested in v3.
	- Simplify compatible property to use contains instead of oneOf.
	- Validate fallback and non-fallback DT. Also validate binding with
          dt_binding_check.
Changes in v3:
	- Add description for Agilex5 Device
	- Add and define fallback to "intel,agilex-soc-fpga-mgr"
	- Validate against Agilex and Stratix10 (non-fallback) and Agilex5
	  (fallback)
Changes in v2:
	- No changes in this patch
