Title: Backport of Chris Boot's i2c and spi drivers.

This is a backport of i2c and spi drivers from Chris Boot (http://www.bootc.net/projects/raspberry-pi-kernel/#Using_SPI_or_I2C). He is unwilling to support the drivers on kernel 3.1.9 for the reasons expressed on his website. However, it might be useful for some to have these drivers included in the official image.
