Patch from Eric Norum:

While trying to work through this problem I decided that the
build-time selection of the console I/O operation (polling or
interrupt) was too clumsy. Here's a patch that allows run-time
(actually init-time) selection of the console I/O mode.

It also shows the need for another flags' or options' field in
the rtems_driver_address_table structure...
