Why do we need MMC options in common? Only keystone device that uses MMC
is Galileo. This should stay in individual device specific or
board specific config file.

Same here..

I believe currently keystone doesn't use GPIO, but this may change.
Probably remove this as well for now and add it when GPIO is supported
on K2.
