Subject: i2c: i2c-mux-pca954x: fix deselect enabling for device-tree

From: Alex Hemme <ahemme@cisco.com>

commit ad092de60f865c1ad94221bd06d381ecea446cc8 upstream.

Deselect functionality can be ignored for device-trees with
"i2c-mux-idle-disconnect" entries if no platform_data is available.
By enabling the deselect functionality outside the platform_data
block the logic works as it did in previous kernels.
