[POWERPC] Create modalias file in sysfs for of_platform bus
Create /sys/bus/of_platform/devices/*/modalias file to allow autoloading of modules. Modalias files are already present for many other bus types. This adds also a newline to the devspec files. Also create a devspec file for mac-io devices. They were created as a side effect. Use correct buffer size for mac-io modalias buffer. Tested on iBook1 and Efika.
