* Makefile.am, configure.ac, console/uart.c, startup/bspstart.c: Use
	standardized bsp_cleanup() which can optionally print a message, poll
	for user to press key, and call bsp_reset(). Using this eliminates
	the various bsp_cleanup() implementations which had their own
	implementation and variety of string constants.
	* startup/bspreset.c: New file.
	* startup/bspclean.c: Removed.
