* 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.
