ASoC: tlv320aix31xx: Add ACPI match for Lenovo 100S 



The Lenovo 100S netbook has a codec controller for which there is a
driver, but doesn't know how to access the device. This adds the
necessary ACPI table for the driver to find the device.

Device (TTLV)
{
    Name (_ADR, Zero)  // _ADR: Address
    Name (_HID, "10TI3100")  // _HID: Hardware ID
    Name (_CID, "10TI3100")  // _CID: Compatible ID
    Name (_DDN, "TI TLV320AIC3100 Codec Controller ")  // _DDN: DOS Device Name
    Name (_UID, One)  // _UID: Unique ID
