This patch adds a I2C bus on which the I2C devices and drivers register.
This makes it cleaner as I2C devices won't accidently end up probed by
a platform_device driver.

The stmpe mfds can be connected via i2c and spi. This driver provides the basic
infrastructure for the i2c kind. It can be added as a normal i2c-device in the
board code. To enable functions a platform_data struct has to be provided, that
describes what parts of the chip are to be used.
