Here's an updated mapping filled out with the rest of the platforms
and using SoC family names in some cases as discussed. The move is
completely scripted now including include fixups (though any new
includes could break things). So mainly just need to bikeshed the
directory mapping. Not sure if marvell should be split up more or not.
I split out pxa2xx and pxa3xx, but then there's other pxa chips I
think aren't really related. TI is still all one directory except
nspire. I was going to split out davinci too, but it's only a couple
of files. Sub-arch maintainers need to chime in with what they want.

A branch is here including a fix to dtbs_install:
