[PATCH 3.16.y-ckt 075/126] ideapad-laptop: Add Lenovo Yoga 900 to no_hw_rfkill dmi list

[Luis Henriques]

3.16.7-ckt21 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@xxxxxxxxxx>

commit f71c882dd4cfe4aa88ea07b1402ddd43605d4aef upstream.

Like some of the other Yoga models the Lenovo Yoga 900 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 900 to the no_hw_rfkill dmi list, fixing
the wifi breakage.
