That's what happens anyway - we add /all/ the CRTCs first before we
start adding the connectors.

That means the CRTCs will be bound before the connectors (ldb).

What you're probably missing is that with what's in my branch, if you
want both CRTCs or the second CRTC in the IPU pair, you must specify
both in the "crtcs" property - iow "crtcs = <&ipuX 0>, <&ipuX 1>".
The reason is there's no way to differentiate the individual platform
devices there without delving into the platform data.
