[ Upstream commit 71936a6d18c33c63b4e9e0359fb987306cbe9fae ]
Specify 'i2c-mux-idle-disconnect' for both I2C switches present on the
board, since both are connected to the same parent bus and all of
their children have the same I2C address.
Fixes: ca4b4d373fcc ("ARM: dts: vf610: Add ZII SCU4 AIB board")
