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.
