[media] em28xx: fix I2S audio sample rate definitions and info output
The audio configuration in chip config register 0x00 and eeprom are always consistent. But currently the audio configuration #defines for the chip config register say 0x20 means 3 sample rates and 0x30 5 sample rates, while the eeprom info output says 0x20 means 1 sample rate and 0x30 3 sample rates. I've checked the datasheet excerpts I have and it seems that the meaning of these bits is different for em2820/40 (1 and 3 sample rates) and em2860+ (3 and 5 smaple rates). I have also checked my Hauppauge WinTV USB 2 (em2840) and the chip/eeprom audio config 0x20 matches the sample rates reproted by the USB device descriptor (32k only).
