imx-drm mode fixup support, imx-hdmi bridge conversion and imx-drm cleanup

- Implement mode_fixup for a DI vertical timing limitation
- Use generic DRM OF helpers in DRM core
- Convert imx-hdmi to dw_hdmi drm_bridge and add rockchip
  driver
- Add DC use counter to fix multi-display support
- Simplify handling of DI clock flags
- A few small fixes and cleanup

+DesignWare HDMI bridge bindings
+
+Required properties:
+- compatible: platform specific such as:
+   * "snps,dw-hdmi-tx"
+   * "fsl,imx6q-hdmi"
+   * "fsl,imx6dl-hdmi"
+   * "rockchip,rk3288-dw-hdmi"
+- reg: Physical base address and length of the controller's registers.
+- interrupts: The HDMI interrupt number
+- clocks, clock-names : must have the phandles to the HDMI iahb and isfr clocks,
+  as described in Documentation/devicetree/bindings/clock/clock-bindings.txt,
+  the clocks are soc specific, the clock-names should be "iahb", "isfr"
+-port@[X]: SoC specific port nodes with endpoint definitions as defined
+   in Documentation/devicetree/bindings/media/video-interfaces.txt,
+   please refer to the SoC specific binding document:
+    * Documentation/devicetree/bindings/drm/imx/hdmi.txt
+    * Documentation/devicetree/bindings/video/dw_hdmi-rockchip.txt
+
+Optional properties
+- reg-io-width: the width of the reg:1,4, default set to 1 if not present
+- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+- clocks, clock-names: phandle to the HDMI CEC clock, name should be "cec"

+- reg: Physical base address and length of the controller's registers.
+- clocks: phandle to hdmi iahb and isfr clocks.
