    nb/intel/sandybridge/raminit: Allow 933Mhz on Lenovo devices
    
    Set max_mem_clock_mhz in devicetree to 933Mhz.
    Allows to run the memory at up to DDR3-1866.
    
    The same frequency was allowed within the first vendor bios,
    but Lenovo than decided to limit it to DDR3-1333.
    
    Tested on Lenovo T520 and DDR3-1600 DIMM (RMT3170eb86e9w16).
    
    The RAM is now running at DDR3-1600 instead of DDR3-1333.
    This gives about 4% performance increase in glmark2 using the
    Intel GPU.
