bonding: add the debugfs facility to the bonding driver
This patch provides the debugfs facility to the bonding driver.
The "bonding" directory is created in the debugfs root and directories of
each bonding interface (like bond0, bond1...) are created in that.
# mount -t debugfs none /sys/kernel/debug
# ls /sys/kernel/debug/bonding
bond0 bond1
