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.
