This commit refactors cleaning targets such as clean, clobber, mrpropper, distclean with scripts/Makefile.clean.
By using scripts/Makefile.clean, we can recursively descend into subdirectories and delete generated files there.
We do not need add a big list of generated files to the "clean" target.

We can delete ugly stuff like follows:
clean: @rm -f examples/standalone/atmel_df_pow2 \ examples/standalone/hello_world \ examples/standalone/interrupt \ examples/standalone/mem_to_mem_idma2intr \ examples/standalone/sched \ $(addprefix examples/standalone/, smc91111_eeprom smc911x_eeprom) \ examples/standalone/test_burst \ examples/standalone/timer @rm -f $(addprefix examples/api/, demo demo.bin) @rm -f tools/bmp_logo tools/easylogo/easylogo \ tools/env/fw_printenv \ tools/envcrc \ $(addprefix tools/gdb/, gdbcont gdbsend) \ tools/gen_eth_addr tools/img2srec \ tools/dumpimage \ $(addprefix tools/, mkenvimage mkimage) \ tools/mpc86x_clk \ $(addprefix tools/, mk$(BOARD)spl mkexynosspl) \ tools/mxsboot \ tools/ncb tools/ubsha1 \ tools/kernel-doc/docproc \ tools/proftool @rm -f $(addprefix board/cray/L1/, bootscript.c bootscript.image) \ board/matrix_vision/*/bootscript.img \ spl/board/samsung/$(BOARD)/tools/mk$(BOARD)spl \ u-boot.lds \ $(addprefix arch/blackfin/cpu/, init.lds init.elf) $(obj)arch/blackfin/cpu/init.{lds,elf}
By the way, I am keeping "make clobber" for now. Do we need "make clobber"? If we like 3-level cleaning targets, clean, mrproper, distclean, like Linux Kernel, we can squash "clobber" to "clean".
