Add kernel Hibernation code for porter board.

This patch set is a support to Hibernation for a porter board.
I've commit with Hibernation Off patch, because it depends strongly on user land.
If you can use Hibernation, Please add local.conf agl-porter-hibernate.
OVERRIDES .= ":agl-porter-hibernate"
DISTRO_FEATURES_append = " agl-porter-hibernate"
