of: make sure of_alias is initialized before accessing it

Simply swap of_alias and of_chosen initialization so
that of_alias ends up read first. This must be done
because it is accessed couple of lines below when
trying to initialize the of_stdout using the alias
based legacy method.

use core stdout parsing code]
