omap3_logic: Change console from ttyO0 to ttyS0

Newer kernels have moved from ttyO0 to ttyS0, and when booting
it drops a notice:

  WARNING: Your 'console=ttyO0' has been replaced by 'ttyS0'
  This ensures that you still see kernel messages. Please
  update your kernel commandline.

This patch updates the console to use ttyS0 and eliminate the
chatter.
