[RFC 1/2] kirkwood: add support for booting via oftree probe

[Alexander Aring]

This patch initialize memory only if we boot a kirkwood arch with
device-tree probing. Otherwise some devices like timer or uart will
be probed twice.

I don't know if this is right. The guruplug is the other kirkwood platform
but don't have devictree support.
