s390/crashdump: move fill_cpu_elf_notes() prototype to header file

Browse Source 
Move fill_cpu_elf_notes() prototype to header file.
This way we get compile errors if e.g. the number of function
parameters get changed.
Otherwise it's possible to change just the definition and everything
else still compiles fine, but the result is broken code.
