Compro VideoMate uses an external audio DSP chip, controlled via tvaudio
module (tda9874a). This patch improves em28xx infrastructure to support
an external audio processor and fixes the Compro VideoMate entry to work
with it.

Several fields are duplicated on both structs. Let's just copy em28xx_board instead.

A later cleanup could just copy the fields that are changed, in order to keep em28xx_board
const.

Empia switched to a 16-bit addressable eeprom in newer devices.  While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms).  So just be safe and bail out of the function.

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Adds autodetection support for the Cinergy200 USB and the VGear PocketTV.

Whenever a usb device with generic empia em2800 usb ids is detected the device
gets scanned for connected i2c devices. If the device list matches an em2800
device in the device list the model id gets changed accordingly.

Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).

This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

Most uses a tda988[5/6/7] IF demodulator as part of the device.
Having this as a separate stuff makes harder to configure it, since there
are some tda9887 options that are tuner-dependent and should be bound into
tuner-types structures.
This patch merges tda9887 module into tuner. More work is required to make
tuner-types to properly use it.

        - 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.
