AFAIK Device Tree property names are considered as ABI, so existing
property names must not be removed.

But I guess we can add the standardized property name in addition
to the deprecated one. New drivers can use the standardized property
name from the beginning.

Thus I guess we should not use the name, which has the most adopters
in kernel (or out of kernel). Instead the most fitting name should
be used. Current suggestions (taken from kernel) are:

* <<vendor>>,no-autorepeat
* keypad,autorepeat
* linux,keypad-no-autorepeat
* linux,input-no-autorepeat
* linux,no-autorepeat
* autorepeat

I do not really care, which one is chosen, except for two things:

* <<vendor>> seems wrong. This is not vendor specific.
* I would prefer "input-" over "keypad-", since then the same name
can be used for single keys, buttons, etc.
