arm64: dts: imx8mm-verdin: add single-master property to all i2c nodes

Browse Source 
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.
