First attempt to clean up SPI probing and create a common construct: the flash bus
At some point the flash bus will be part of struct flashchip.
Pardon me for pushing this in, but I think it is important to beware of further
decay and it will improve things for other developers in the short run.
Carl-Daniel, I will consider your suggestions in another patch. I want to keep
things from getting too much for now. The patch includes Rudolf's VIA SPI
changes though.
Corresponding to flashrom svn r285 and coreboot v2 svn r3401.
