This patch updates file2alias.c to support pnp ids.  It is from
Takashi Iwai <tiwai@suse.de>.

visor.c defines one empty slot in USB ids table that can be filled in at
runtime using module parameters. file2alias generates catch-all alias for it:

alias usb:v*p*dl*dh*dc*dsc*dp*ic*isc*ip* visor

patch adds the same sanity check as in depmod to scripts/file2alias.

Add module alias support for ccw devices.

This adds ieee1394 for module table registration.

The previous handling of PCI class masks was too primitive: the
class field is not "all or nothing" but has base class, subclass
and interface fields.  This patch changes the alias form from:
pci:vNdNsvNsdNcN to pci:vNdNsvNsdNbcNscNiN.

Up to now, we called "nm" to find the symbol table in vmlinux / modules.
Using code from scripts/file2alias.c allows us to do that parsing ourselves,
which is faster and will give us the opportunity to merge the
MODULE_DEVICE_TABLE() parsing into modpost, too.

The helper file2alias had to jump through a lot of hoops because it did not
know the host and target endianness / word size at compile time.
We now build a small header scripts/elfconfig.h which contains this
information for file2alias to use.

Introduces "MODULE_ALIAS" which modules can use to embed their own
aliases for modprobe to use.  Also adds a "finishing" step to modules to
supplement their aliases based on MODULE_TABLE declarations, eg.
'usb:v0506p4601dl*dh*dc*dsc*dp*ic*isc*ip*' for drivers/usb/net/pegasus.o
