arm: tegra: ventana: deselect pca9546 i2c mux channel on exit
On ventana, pca9546 is used as a mux for 0v2710/ov5650 camera
sensors. With UJA0H14 version of ov5650 sensor, it is observed
that pca9546 driver incorrectly caches last channel when VDDIO_CAM
is toggled while enabling/disabling tegra camera. Deselect i2c
mux channel on exit so that i2c mux is correctly configured with
new mux channel.
BUG 812134
