[PATCH v7 1/3] dt-bindings: net: can: ifi,canfd-1.0: Convert to DT schema

[Quchaosheng]

Convert the IFI CAN-FD controller binding from free-form text to DT
schema.

Reference can-controller.yaml. interrupts is required: the driver obtains
it with platform_get_irq().

The example now uses the GIC and irq header defines instead of raw numbers.
The values are unchanged: GIC_SPI is 0, IRQ_TYPE_NONE is 0 and 1 is
IRQ_TYPE_EDGE_RISING. Rename the example node from canfd to can so that it
matches the $nodename pattern in can-controller.yaml.

-IFI CANFD controller
---------------------
-
-Required properties:
-  - compatible: Should be "ifi,canfd-1.0"
-  - reg: Should contain CAN controller registers location and length
-  - interrupts: Should contain IRQ line for the CAN controller
-
-Example:
-
-	canfd0: canfd@ff220000 {
-		compatible = "ifi,canfd-1.0";
-		reg = <0xff220000 0x00001000>;
-		interrupts = <0 43 0>;
