[PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/

dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
Currently all three arches compile it from arch/i386, which means that ia64
and x86_64 depend on things in arch/i386 that they wouldn't otherwise care
about.

This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing
trailing whitespace) and the associated Makefile changes.  All three
architectures already set CONFIG_DMI in their top-level Kconfig files.
