[PATCH v3 2/3] dt-bindings: firmware: stratix10: Convert to json-schema

[Mahesh Rao <mahesh.rao@intel.com>]

Convert intel,stratix10-svc service layer devicetree
binding file from freeform format to json-schema.

Also added DT binding for optional stratix10-soc
FPGA manager child node.

-Intel Service Layer Driver for Stratix10 SoC
-============================================
-Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard
-processor system (HPS) and Secure Device Manager (SDM). When the FPGA is
-configured from HPS, there needs to be a way for HPS to notify SDM the
-location and size of the configuration data. Then SDM will get the
-configuration data from that location and perform the FPGA configuration.
-
-To meet the whole system security needs and support virtual machine requesting
-communication with SDM, only the secure world of software (EL3, Exception
-Layer 3) can interface with SDM. All software entities running on other
-exception layers must channel through the EL3 software whenever it needs
-service from SDM.
-
-Intel Stratix10 service layer driver, running at privileged exception level
-(EL1, Exception Layer 1), interfaces with the service providers and provides
-the services for FPGA configuration, QSPI, Crypto and warm reset. Service layer
-driver also manages secure monitor call (SMC) to communicate with secure monitor
-code running in EL3.
-
-Required properties:
--------------------
-The svc node has the following mandatory properties, must be located under
-the firmware node.
-
-- compatible: "intel,stratix10-svc" or "intel,agilex-svc"
-- method: smc or hvc
-        smc - Secure Monitor Call
-        hvc - Hypervisor Call
-- memory-region:
-	phandle to the reserved memory node. See
-	Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
-	for details
-
-Example:
--------
-
-	reserved-memory {
-                #address-cells = <2>;
-                #size-cells = <2>;
-                ranges;
-
-                service_reserved: svcbuffer@0 {
-                        compatible = "shared-dma-pool";
-                        reg = <0x0 0x0 0x0 0x1000000>;
-                        alignment = <0x1000>;
-                        no-map;
-                };
-        };
-
-	firmware {
-		svc {
-			compatible = "intel,stratix10-svc";
-			method = "smc";
-			memory-region = <&service_reserved>;
-		};
-	};
