As well as being able to generate its own i2c transactions, the ppc4xx i2c controller has a DIRECTCNTL register which allows explicit control of the i2c lines. Using this register an OS can directly bitbang i2c operations. In order to let emulated i2c devices respond to this, we need to wire up the DIRECTCNTL register to qemu's bitbanged i2c handling code.
