This converts the v3d bindings to yaml format.

Changes in V4:
- define order for required reg-names
- adapt example
Changes in V3:
- drop redundant maxItems in case we already have items defined
- fix order of reg-names enum
- tag required items in description
- add reg-names to required properties
- drop clock-names

-Broadcom V3D GPU
-
-Only the Broadcom V3D 3.x and newer GPUs are covered by this binding.
-For V3D 2.x, see brcm,bcm-vc4.txt.
-
-Required properties:
-- compatible: Should be "brcm,7268-v3d" or "brcm,7278-v3d"
-- reg: Physical base addresses and lengths of the register areas
-- reg-names: Names for the register areas. The "hub" and "core0"
- register areas are always required. The "gca" register area
- is required if the GCA cache controller is present. The
- "bridge" register area is required if an external reset
- controller is not present.
-- interrupts: The interrupt numbers. The first interrupt is for the hub,
- while the following interrupts are separate interrupt lines
- for the cores (if they don't share the hub's interrupt).
- See bindings/interrupt-controller/interrupts.txt
-
-Optional properties:
-- clocks: The core clock the unit runs on
-- resets: The reset line for v3d, if not using a mapping of the bridge
- See bindings/reset/reset.txt
