openrisc: header file cleanups
elf.h: We can export some of these symbols to userspace. libc needs them and we just as well provide them as asm/elf.h as copying them into separate libc headers. ptrace.h: Having padding in the user_regs_struct isn't of any particular value and just confuses GDB. spr_defs isn't needed in userspace; libc has its own copy anyway.
