mb/google/guybrush,mancomb: only print warning in mainboard_smi_gpi

guybrush and mancomb don't configure any GPIO as PAD_SMI. Since
mainboard_smi_gpi will only get called for a GEVENT that will cause a
non-SCI SMI, this isn't expected to be called. For the unexpected and
very unlikely case that it still does get called, put a printk into
mainboard_smi_gpi to see what is happening there.

TEST=none
