    [PATCH] eeprom_93cx6: shorten pulse timing to match spec
    
    93cx6 datasheet available here:
    
            http://ww1.microchip.com/downloads/en/DeviceDoc/21749F.pdf
    
    Figure 1-1 and Table 1-2 on pages 4-5 indicate that both Clock High
    Time and Clock Low Time have largest minimum times of 450ns.
