skylake: provide GPE0 routing devicetree configuration

On skylake the GPE0 routing can be dynamically changed to
    a particular GPIO group. Provide the ability for the mainboard
    to set the route accordingly. If any of the values in the
    devicetree are the same the current setting in the PMC register
    is used. The GPIO communities need to have matching configuration
    for the plumbing to work properly.

BUG=chrome-os-partner:43778
    BRANCH=None
    TEST=Built and booted glados w/ and w/o devicetree changes. Fields
         are set accordingly.
