[PATCH] MIPS: ingenic: JZ4725B: Add IPU node

[Paul Cercueil]

Add a devicetree node for the Image Processing Unit (IPU) found in the
JZ4725B. Connect it with graph nodes to the LCD node. The LCD driver
will expect the IPU node to be accessed through graph port #8, as stated
in the bindings documentation.

Notes:
    Binding documentation was merged in the DRM tree (drm-misc-next branch).
    See https://cgit.freedesktop.org/drm/drm-misc/plain/Documentation/devicetree/bindings/display/ingenic,ipu.yaml

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
