MPC8xx CPM I2C interface driver

Yes indeed. I got i2c-algo-8xx.c from 2005-August. Also in the mail archives there
are some patches to this file and the I2C RPX adapter (which is about the only one
using I2C algo 8xx).
Btw. One of the changes had to do with I2C RPX adapter not requesting the I2C IRQ
since I2C algo is already doing that.

Anyway, it all seems to work now.

Thanks.
