[PATCH] ARM: dts: sun7i: Change cubietruck wifi enable pin to use mmc-pwrseq

[Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

The wifi-enable pin of the ap6210 module is not really a regulator,
switch to the mmc-pwrseq framework for controlling it. This more
accurately reflects how the hardware actually works.
