[PATCH] omap3-n900.dts: Rename model name to "Nokia RX-51 board"

[Pali Rohár]

Use same name as in legacy board code. There are lot of userspace applications
which using machine/model name for determinating device type. And changing this
name will break all of them. Due to small features support in DT code only non
DT kernel was used for Nokia N900 until now.

Can you clarify this? Nokia kernel or userspace never had DT, so they
cannot see e.g. /proc/device-tree/model. What other APIs expose model?

Hi Aaro,

look at email discussion about my previous patch with subject:
[PATCH] ARM: /proc/cpuinfo: Use DT machine name when possible

Basically that patch export model name in Hardware /proc/cpuinfo 
instead generic DT name. And this patch change name to what 
legacy board code reported.

I don't like the idea of changing the model name from Nokia
marketing names to those cryptic internal names in DT files.
There also may be already some userspace relying to find current model
name from /proc/device-tree/model (e.g. I think my own OS would break).
