ARM: S3C64XX: Use module identification for Cragganmore system builds
The Cragganmore system is modular with I2C based identification chips on the system allowing identification of the system build. Provide a stub I2C driver which parses the module IDs and uses them to select the appropriate audio subsystem components to register. To avoid confusion due to having the mini-driver in the system the driver is placed in a separate file.
