Add spiflash driver, and M25P instance, used for STMicro flash devices found on Meraki Mini (for example).

# $NetBSD: files.spi,v 1.2 2006/10/07 07:21:13 gdamore Exp $
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.
