Please Back commit out.  You broke the console on the most modern Sparc
machines we run^H^Hran on.  Commenting out uart adding back
ofw_console(4) restore console on Sun Blade 1{0,5}0 machines.  Just
adding back ofw_console(4) restores console output, but ofw_console(4)
and uart(4) fight for input.

Contrary to rev 1.88's claim, ofw_console(4) does not cause harm, and NO
uart(4) has not completely handled its functionality.
