    google/reef: Enable 20K pull ups for LPC CLKRUN and LAD0:3 lines
    
    The pull up for CLKRUN is required to resolve keyboard slowness
    and malfunctioning observed on some reef systems. The CLKRUN
    signal was probed and found to be floating when the pull up
    was not enabled. Also Added pull ups for the LPC Multiplexed
    command, address and data lines LAD0:3 because the LPC
    Interface specification requires them.
    
    BUG=chrome-os-partner:55586
    BRANCH=none
    TEST=When a key is pressed, the character is immediately visible
         on the screen. Also the interrupt count for i8042 increments
         immediately in /proc/interrupts.
