When running a 'make clean' or carelessly removing u-boot.cfg, all future make invocations (until autoconf is regenerated) will print an error for a missing u-boot.cfg due to missing rules and dependencies.
This commit adds (i) an explicit rule dependency from all (which will invokes the configuration checker) to cfg, and (b) adds a rule to invoke scripts/Makefile.autoconf to regenerate u-boot.cfg.
