Subject: panel-dsi-cm: update bindings

The cleanup series for omapdrm's DSI code got too big. Reviewing
this is not fun and the same goes for keeping track of the change
requests. Let's do the cleanup in smaller steps instead. This is
the first batch, which updates the binding (txt -> yaml) and
modifies the DT slightly.

The standard binding for DSI requires, that the channel number
of the panel is encoded in DT. This adds the channel number in
all OMAP3-5 boards, in preparation for using common infrastructure.

Add Droid 4 specific compatible value in addition to the
generic one, so that we have the ability to add panel
specific quirks in the future.

Thanks, one of the few panel bindings still pending.
And you added some nice explanations too, good.

Some small comments in the folllowing.

Later port: is required which does not really match this explanation.

My personal preference is indent 4 spaces.
But there is no hard rule so do what you like.

Addding the port node here does not really help me,
I was left confused about the lanes = <...> property.

This use of label does not really match the description.
The description says label shall be used for specific names and not
generic names like "lcd".

Add:
<empty line>
...

The latter is end of statement or soething.
You see it used often bu not always.

I expect it to become mandatory the day the tools check for it.
