Allocate channel structures as part of the softc rather than malloc'ing them at run time. This simplifies the code and avoids problems with uninitialised variables, and if it's good enough for pciide(4), it's good enough for me. Also normalise the prefix for channel-specific messages.

/* $NetBSD: icsidereg.h,v 1.3 2002/09/15 11:00:11 bjh21 Exp $ */
Initial commit of the splitting off of arch/acorn32 from arch/arm32. The IOMD/VIDC combination is now moved to arch/arm/iomd together. These files still need a lot of cleaning up :( .... esp. the RC7500 support that is still dormant in it; this needs either to be removed or split out for RC7500's ``VIDC'' video/audio variant. Apart from the RC7500 support wich is still in arch/arm32 the iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed. This split still uses some small parts of arch/arm32 .... those are the MI parts that haven't been moved yet. RiscPC/A7000 have been tested and confirmed to build as should NC.

On ARCIN v6 cards, clear the EPROM page latch on shutdown. This seems to be necessary to allow the card to be detected afterwards. In theory, this shouldn't be necessary, since we don't touch the page latch yet, but I'm not going to argue.
