Added Files:
        src/sys/dev/spi: files.spi spi.c spivar.h tmp121.c

Log Message:
Initial commit of SPI bus (also known as Microwire) framework, along with
a sample driver for the TI TMP121 temperature sensor.  This has been
moderately tested on Au1550, and it is not enabled in sys/conf (yet).  So
the change is harmless at worst, and useful at best.

Alchemy Au1550 bus driver forthcoming, along with a driver for SPI flash
devices, such as found on the Meraki Mini

This development was partially funded by the Champaign-Urbana Community
Wireless Network Project.

Note that there are some MD-specific SPI drivers that could probably be
made MI under this new framework.
