[ Upstream commit 647c8977e111c0a62c93a489ebc4b045c833fdb4 ]
According to
Documentation/devicetree/bindings/i2c/i2c-mux-pca954x.txt,
i2c-mux-idle-disconnect is a property of a parent node since it
pertains to the mux/switch as a whole, so move it there and drop all
of the concurrences in child nodes.

[ 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.
