[SERIAL] sunsab: Fix E250 console with RSC.
This fixes yet another sunsab problem, when console is set to anything
but the first port. The console framework calls sunsab_console_setup
for each port, and we end up setting up a console on a not yet
discovered port, which leads to an Oops. Instead, defer console setup
until the requested port is properly initialized. Tested on an E250
through an RSC console.
