Nothing but I decided to set it similarly as I2C, another more common 
bus. IIRC same was for I2C_MUX too.

You could still disable media subdriver autoselect and then disable SPI 
and select all the media drivers (excluding MSSi2500) manually.

I have feeling that media auto-select was added to select everything 
needed for media.
