skylake: Enable DDI-A 4-lane support if GOP does not execute

This change will allow the kernel to use 4-lane eDP connections
    if the GOP driver does not execute and set this bit.  If GOP
    has executed (everyone but Chrome OS verified mode) the link will
    already be up and this will do nothing.
