Currently all paths passed to of_find_node_by_path() must begin with a
'/', indicating a full path to the desired node.
Augment the look-up code so that if a path does *not* begin with '/',
the path is used as the name of an /aliases property. The value of
this alias is then used as the full node path to be found.

All the aliases are already decoded at boot time now. See
of_alias_scan(). Instead of open-coding this, you can add an
of_alias_lookup() function something like this (untested):
After objections from davem, and a bit of thought, I already indicated
on a different branch of this thread that we should drop this patch.
I have improved my code so that it is no longer needed.
Thanks,
