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
