Converts net/cortina,gemini-ethernet.txt to yaml
This permits to detect some missing properties like interrupts

-Cortina Systems Gemini Ethernet Controller
-==========================================
-
-This ethernet controller is found in the Gemini SoC family:
-StorLink SL3512 and SL3516, also known as Cortina Systems
-CS3512 and CS3516.
-
-Required properties:
-- compatible: must be "cortina,gemini-ethernet"
-- reg: must contain the global registers and the V-bit and A-bit
- memory areas, in total three register sets.
-- syscon: a phandle to the system controller
-- #address-cells: must be specified, must be <1>
-- #size-cells: must be specified, must be <1>
-- ranges: should be state like this giving a 1:1 address translation
- for the subnodes
-
-The subnodes represents the two ethernet ports in this device.
-They are not independent of each other since they share resources
-in the parent node, and are thus children.
-
-Required subnodes:
-- port0: contains the resources for ethernet port 0
-- port1: contains the resources for ethernet port 1
-
-Required subnode properties:
-- compatible: must be "cortina,gemini-ethernet-port"
-- reg: must contain two register areas: the DMA/TOE memory and
- the GMAC memory area of the port
-- interrupts: should contain the interrupt line of the port.
- this is nominally a level interrupt active high.
-- resets: this must provide an SoC-integrated reset line for
- the port.
-- clocks: this should contain a handle to the PCLK clock for
- clocking the silicon in this port
-- clock-names: must be "PCLK"
-
-Optional subnode properties:
-- phy-mode: see ethernet.txt
-- phy-handle: see ethernet.txt
