dev/tsunami.cc:
Changed so Tsunami has a pointer to the System to which it belongs.
Now it is derived from generic base class Platform so platform stuff
can be accessed based on the system
dev/tsunami_io.cc:
dev/tsunami_io.hh:
Cleanup and added copyright
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
Added event to skip the "calibrate_delay" function, now calculate
loops_per_jiffy based on frequency, interrupt frequency, and constant
sim/system.hh:
Added pointer to generic Platform base class
