From: Stefan Eichenberger <stefan.eichenberger@toradex.com>

By default we expect all i2c nodes to be single-master, we do not have
any module or carrier board that uses multi-master mode on any i2c
controller. With this property set, we benefit from optimisations made
exclusively for single-masters.
