ARM: dts: msm: Enable symmetry in Lahaina led switch devices

Browse source 
On platforms where the led channels are connected pair-wise, enabling
symmetry causes the requested led current to be distributed equally
amongst them.

This is required because internally, the paired led channels are pulled
down by default, and turning only one of them on can cause some leakage
current to drain to the one that is off.
