sysfs: Add attribute array to sysdev classes

Browse Source 
Add a attribute array that is automatically registered and unregistered
to struct sysdev_class. This is similar to what struct class has.

A lot of drivers add list of attributes, so it's better to do 
this easily in the common sysdev layer.

This adds a new field to struct sysdev_class. I audited the 
whole tree and there are no dynamically allocated sysdev classes,
so this is fully compatible.
