[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.
