x86/acpi_device: Fix writing of array property

Only acpi_dp of type DP_TYPE_TABLE is allowed to be an array. This
    DP_TYPE_TABLE does not have a value which is written. Thus,
    acpi_dp_write_array needs to start counting from the next element type
    in the array. Fix this by updating the initialization in for loop for
    writing array elements.

BUG=chrome-os-partner:55988
    BRANCH=None
    TEST=Verified that the correct number of elements are passed for
    add_gpio in maxim sdmode-gpio.
