Changed timer functionality, ide disk interrupts, and TsunamiFake class to improve FreeBSD compatibility.

dev/ide_disk.cc:
    Make ide disk set interrupts correctly.
dev/tsunami_io.cc:
dev/tsunami_io.hh:
    Implement read of timer counts.
kern/freebsd/freebsd_system.cc:
kern/freebsd/freebsd_system.hh:
    Remove SkipFuncEvents that we don't need to skip.
python/m5/objects/Tsunami.py:
    Add size parameter to TsunamiFake class.
