* shared/bspstart.c, shared/start.S: Use common clock driver template
	and eliminate all fast idle code specific to this BSP. This
	eliminates a fair amount of code in the BSP clock driver and
	bsp_startup. The LEON3 has to do a scan of the AMBA bus to find the
	timer so I added the new hook Clock_driver_support_find_timer to
	support this. In general, there was some clean up to the file headers
	of various files.
