    usb: Prepare cleanup of powerpc's asm/prom.h

    powerpc's asm/prom.h brings some headers that it doesn't
    need itself.

    In order to clean it up in a further step, first clean all
    files that include asm/prom.h

    Some files don't need asm/prom.h at all. For those ones,
    just remove inclusion of asm/prom.h

    Some files don't need any of the items provided by asm/prom.h,
    but need some of the headers included by asm/prom.h. For those
    ones, add the needed headers that are brought by asm/prom.h at
    the moment, then remove asm/prom.h

    Some files really need asm/prom.h but also need some of the
    headers included by asm/prom.h. For those one, leave asm/prom.h
    but also add the needed headers so that they can be removed
    from asm/prom.h in a later step.
