This 'could' be usefull to speed up the i2c communication if there are more 
than one i2c devices with significant differences between the clock timing; 
ex. 27C32 (100kHz at 3.3V) and LM75 (400kHz). Tolunay has spoken about like 
this. But right I see now reason to do so, too. U-Boot has to be a boot 
loader not a performant operator...
