[PATCH] [POWERPC] i2c: adds support for i2c bus on 8xx

Using the port of 2.4 code from Vitaly Bordug [off-list ref]
and the actual algorithm used by the i2c driver of the DBox code on
cvs.tuxboc.org from Tmbinc, Gillem (htoa@gmx.net). Renamed
i2c-algo-8xx.c to i2c-algo-cpm.c and i2c-rpx.c to i2c-8xx-of.c. Added
original i2c-rpx.c as i2c-8xx.c for pre-OF (arch ppc) devices.
