ruby: interface with classic memory controller

This patch is the final in the series.  The whole series and this patch in
particular were written with the aim of interfacing ruby's directory controller
with the memory controller in the classic memory system.  This is being done
since ruby's memory controller has not being kept up to date with the changes
going on in DRAMs.  Classic's memory controller is more up to date and
supports multiple different types of DRAM.  This also brings classic and
ruby ever more close.  The patch also changes ruby's memory controller to
expose the same interface.
