V4L/DVB (6212): pvrusb2: I2C adapter tweaks from Jean Delvare
* I2C adapters aren't expected to handle I2C_M_NOSTART unless they
really have to. As the pvrusb2 driver doesn't support it, I take it
that it doesn't need it so it shouldn't mention it at all.
* I2C_FUNC_SMBUS_EMUL includes I2C_FUNC_SMBUS_BYTE_DATA so listing
both is redundant.
