This commit adds a DEBUG_FS dependent DSA core file creating a generic
debug filesystem interface for the DSA switch devices.
The interface can be mounted with:
# mount -t debugfs none /sys/kernel/debug
The dsa directory contains one directory per switch chip:
# cd /sys/kernel/debug/dsa/
# ls
switch0 switch1 switch2
Each chip directory contains one directory per port:
# ls -l switch0/

Future patches will add entry files to these directories.
