While I agree with the change in general, I can't find anything which
reuses that code. So the change log is pretty useless and I have no idea
how

netif_stop_queue()/netif_wake_qeue() aren't needed for changing
multicast filters. Use spinlocks instead for proper protection

Buffers alloacted by alloc_skb() are already cache aligned so there
is no need for an extra align done by ioc3_alloc_skb. And instead
of skb_put/skb_trim simply use one skb_put after frame size is known
during receive.

Break up the big ioc3 register struct into functional pieces to
make use in sub-function drivers more straightforward. And while
doing that get rid of all volatile access by using readX/writeX.

IOC3 chips in SGI system are conntected to a bridge ASIC, which has
a 1-wire prom attached with part number information. This changeset
uses this information to create PCI subsystem information, which
the MFD driver uses for further platform device setup.
