[PATCH v2] usb: Prepare cleanup of powerpc's asm/prom.h

From: Christophe Leroy
Date: Fri Apr 15 2022 - 04:34:43 EST


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.
