[POWERPC] coredump: Add SPU elf notes to coredump.
This patch adds SPU elf notes to the coredump. It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.
