[spigen] add initial spigen driver from green@

This is a simple ioctl and mmap API to issue SPI transactions from
userland. It's useful for simple devices (eg spi temperature sensors,
etc) for experimentation.

TODO:

* Write some documentation!

Submitted by: green

Add copyright statement I should have had on these files in 2006,
based on the spibus_if.m file.

Fetch the chip select in the bridge driver, like all the other spi
bridges do.

Add the chip select glue.

Fix comments.

MFp4:
Initial spibus support. Seems to be OK, but needs some polish.

# someone should write a bit-bang spi parallel port interface :-)
