A780/E680: SPI driver using hardware SPI controllers working

So apparently there is no obvious reason for Motorola's driver using bit-banging rather than the controllers inside the PXA270. I now have a modified Motorola driver on 2.6.16.5 running that uses the SPI controller for the bus to PCAP2. Getting my own driver running should therefore be quite fast now.

I've also hacked a bit on the keyboard side, although it's not working yet.
