Disable bridge multicast snooping (IGMP/MLD) by default

The Marvell mv88e6xxx switch driver currently used in active projects do
not support multicast router ports properly yet.  Considering that Infix
do not yet have YANG support for configuring IGMP/MLD snooping, we have
decided to disable it in bridge setups by default.
