[PATCH 1/6] vme: remove ca91cx42 Universe-II support

[Arnd Bergmann <arnd-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>

This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.

As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.

The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.

If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.
