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.
[Fixes a752ee5
- tty: Update hypervisor tty drivers to
use core stdout parsing code]
