- change argument from "char *" to "void *" setup_initial_init_mm()
suggested by Geert Uytterhoeven
- use NULL instead of (void *)0 on h8300 and m68k

I might be missing something, but AFAIU the init_mm.start_code and other
fields are not used really early so the new setup_initial_init_mm()
function can be called in the generic code outside setup_arch(), e.g in
mm_init().
Hi Mike， each architecture has their own value, not the same, eg m68K and
h8300, also the name of the text/code/brk is different in some arch, so
I keep
unchanged.
