ARM: dts: aspeed: catalina: Enable multi-master on additional I2C buses

Update the device tree to enable `multi-master` mode on I2C buses shared
between the host BMC and the NV module with HMC. This ensures proper bus
arbitration and coordination in multi-master environments, preventing
communication conflicts and improving reliability.
