PciDev and IntDev stuck out as the only device classes that ended in 'Dev' rather than 'Device'. This patch takes care of that inconsistency. Note that you may need to delete pre-existing files matching build/*/python/m5/internal/param_* as scons does not pick up indirect dependencies on imported python modules when generating params, and the PciDev -> PciDevice rename takes place in a file (dev/Device.py) that gets imported quite a bit.
