ARM: dts: aspeed: catalina: add i2c-mux-idle-disconnect to all mux
Add the `i2c-mux-idle-disconnect` property to all i2c-mux nodes to
ensure proper behavior when switching between multiple I2C buses.
This avoids potential confusion caused by device addresses appearing on
multiple buses when they are not actively selected.
