I've just tried to rebuild target's rootfs with your .config and only 
see 1 instance of ttyAMx:
===
# Put a getty on the serial port
ttyAM0::respawn:/sbin/getty -L ttyAM0 57600 vt100 # GENERIC_SERIAL
===

So I have no ideas on where another 2 got from in your case.

Also below is configuration I used (got it with "make savedefconfig" 
from your .config):
