nb/intel/sandybridge/raminit: Add Kconfig option for fuses
Add a new Kconfig option to ignore memory fuses that limit the maximum DRAM frequency to be used. The option is disabled by default and should only enabled by experienced users as it might decrease system stability or prevent a successful RAM training. Remove conflicting devicetree settings.
