[PATCH] v4l: 784: several improvement on i2c ir handling for em2820 

- Several Improvement on I2C IR handling for em2820:
        - moved Pinnacle IR table (ir_codes_em2820) to em2820-input.c
        - IR struct renamed and moved to a header file.
        - New file to handle em2820-specific IR.
        - Some cleanups.
        - attach now detects I2C IR and calls em2820-specific IR code
        - IR compat code moved to compat.h
        - New header with struct IR_i2c there, to allow it to be
          used by board-specific input handlers.

- Some improvements at em28xx board detection:
        - Board detection message improved to show interface and class.
        - Now it doesn't touch audio interfaces.
