nb/sandybridge: Move MRC cache above mrc.bin 

This small change greatly reduces CBFS fragmentation. There is now a
small gap of only 728 bytes between mrc.bin and mrc.cache, with the
64 KiB alignment maintained for mrc.cache -- assuming systemagent-r6
is used. The gap was just under 64 KiB before.

With this change, it is easier to accommodate fallback and normal
boot stages without having to manually place the stages in the highly
fragmented CBFS.
