skylake: make PAD_CFG_GPI default to GPIO ownership

The prior implementation of PAD_CFG_GPI kept the pad
    ownership as ACPI. The gpio driver in the kernel then
    wouldn't allow one to export those GPIOs through sysfs
    in /sys/class/gpio. Fix this by setting the ownership
    to GPIO.

BUG=chrome-os-partner:44147
    BRANCH=None
    TEST=Built and boot glados. PCH_WP gpio is properly exported
         by crossystem.
