skylake: Add I2C devices

Add the I2C devices to skylake with the scan_bus handler for SMBUS
    devices so that I2C-based devices can be declared in devicetree.cb
    and get initialized properly during ramstage.

This does not yet provide the I2C driver, but it allows for devices
    that are declared in devicetree.cb to provide ACPI tables to the OS.
