mb/google/octopus: Enable mode change as wake source from S3/S0ix

This change enables mode change as a wake source from S3 and
S0ix. Thus, any time the device switches between clamshell and tablet
mode while it is suspended, it will be treated as a valid user event
and hence wake source.

BUG=b:120349473
BRANCH=octopus
TEST=Verified that octopus wakes up on mode transitions.
