mem-ruby: functions for connecting sequencer ports

Added functions for connecting the sequencer and cpu ports.
Using these functions instead of wiring up the ports directly allow
protocols to provide specialized sequencer implementations. For
instance, connecting the cpu icache_port and dcache_port to
different sequencer ports or to different sequencers.

A follow-up patch will update the configurations to use these
functions.
