apalis-tk1: fix wake on lan functionalityApalis-TK1_LXDE-Image_2.8b1.64-20171229
GPIO used for WOL is briefly used in i210 reset procedure. This patch makes sure it's freed and can be used for a wakeup source. Signed-off-by: Dominik Sliwa <dominik.sliwa@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
