IEEE-1275 spec compliance. This patch implements the following: 1) Fix bootpath/bootargs handling so that default values are read from NVRAM, and allow multiple space-separated values to be specified. 2) With correct bootargs handling in place, move the ELF loader over to the new libopenbios unified loaders. 3) Remove all the loader code from all architecture directories sine we don't need it anymore. 4) Simplify the boot word so it invokes platform-specific code where required, then calls load and go as per the specification. Tested on all my available images for SPARC32, SPARC64 and PPC, and compile-tested on x86.
