i386 arch subdivision into machine types

This code rearranges the arch/i386 directory structure to allow for sliding additional non-pc hardware in here in an easily separable (and thus easily maintainable) fashion. The idea is that all the code for the particular problem hardware should be able to go in a separate directory with only additional build options in config.in.

The current patch really only pulls out the visws code from the core and places it into a separate directory (sort of a simple example case). It also creates a generic directory (for standard x86 PCs) with all of the hooks documented.

This code is a merger with the Patrick Mochel/Dave Jones setup and cpu split. It also includes documentation for all of the created hooks inside arch/i386.

Now that Linus has taken Patricks large reorganisation, I think we're
ready to start looking at this. I'll experiment with it a little when
I get around to syncing against 2.5.21
