i2c: pca954x: Add option to skip disabling PCA954x Mux device
On some Layerscape boards like LS2085ARDB/LS2080ARDB,
input pull-up resistors on PCA954x Mux device are
missing on board. So, if mux are disabled after powered-on,
input lines will float leading to incorrect functionality.
Hence, PCA954x Mux device should never be turned-off after
power-on.
Add option to skip disabling PCA954x Mux device
if device tree contians "i2c-mux-never-disable" property
for pca954x device node.
