ARM: dts: quanta: i2c-2 idle disconnects
Two top-level pca954x muxes branch off Quanta q71l i2c-2 bus; they
have different addresses, so there is no confusion in that sense.
However, by default, the pca954x driver skips disconnecting the
selected channel. This supports expected topologies, but will leave
two channels selected at the same time when connected in parallel.
This commit adds the i2c-mux-idle-disconnect property to both muxes
to inform the driver that disconnecting is not optional on bus 2.
