mcf52235/startup/bspclean.c, mcf52235/startup/bspstart.c,
mcf52235/startup/linkcmds, mcf52235/timer/timer.c: Cleaned up
white space and code formmated to adhere to RTEMS standards. Fixed
a bug in the nano seconds since last tick support. Fixed a bug
with the location of the start stack (no longer within
.bss). Removed double definition of IPSBAR and some type defs
etc.. Added timing test overhead results.
