convert the binding file rockchip-drm.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml

the detail of the ARM tests:
export ARCH=arm KBUILD_OUTPUT=../kbuild/arm-test-dtc/ CROSS_COMPILE=arm-linux-gnueabi-
make menuconfig # set rockchip system
make clean
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml

the detail of the ARM64 tests:
export ARCH=arm64 KBUILD_OUTPUT=../kbuild/arm64-test-dtc/ CROSS_COMPILE=aarch64-linux-gnu-
make menuconfig # set rockchip system
make clean
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml


Changes since v1:
- fixed worng sign-off
- fixed the path of the $id property to be the path of the yaml file
Changes since v2:
- add a missing ">" sign in maintainers list
- change the licens to GPL-2.0-only
- add "additionalProperties: false"
- change the commit message to conform that it was tested on both ARM and ARM64

-Rockchip DRM master device
-================================
-
-The Rockchip DRM master device is a virtual device needed to list all
-vop devices or other display interface nodes that comprise the
-graphics subsystem.
-
-Required properties:
-- compatible: Should be "rockchip,display-subsystem"
-- ports: Should contain a list of phandles pointing to display interface port
-  of vop devices. vop definitions as defined in
-  Documentation/devicetree/bindings/display/rockchip/rockchip-vop.txt
