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.
