Subject: [PATCH 1/2 v2] of: move phandle/ihandle into types.h and export to
 userspace


We need phandle for some exported sparc headers; of.h isn't an
exported header, and it would be silly to export it when all we
really need is one or two types from it.  Also, later patches
use phandle in structs that are exported to userspace, so export
a __kernel_phandle type.
