This converts the Faraday FOTG210 OTG USB controller to use
a YAML schema. We add all the right includes for OTG controllers
and make it possible to specify dr_mode and phy.

-Faraday FOTG Host controller
-
-This OTG-capable USB host controller is found in Cortina Systems
-Gemini and other SoC products.
-
-Required properties:
-- compatible: should be one of:
-  "faraday,fotg210"
-  "cortina,gemini-usb", "faraday,fotg210"
-- reg: should contain one register range i.e. start and length
-- interrupts: description of the interrupt line
-
-Optional properties:
-- clocks: should contain the IP block clock
-- clock-names: should be "PCLK" for the IP block clock
-
-Required properties for "cortina,gemini-usb" compatible:
-- syscon: a phandle to the system controller to access PHY registers
-
-Optional properties for "cortina,gemini-usb" compatible:
-- cortina,gemini-mini-b: boolean property that indicates that a Mini-B
-  OTG connector is in use
-- wakeup-source: see power/wakeup-source.txt
-
-Example for Gemini:
-
-usb@68000000 {
-	compatible = "cortina,gemini-usb", "faraday,fotg210";
-	reg = <0x68000000 0x1000>;
-	interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&cc 12>;
-	clock-names = "PCLK";
-	syscon = <&syscon>;
-	wakeup-source;
-};
