orinoco: encapsulate driver locking

Browse source 
Local bus and USB drivers will need to do locking differently.

The original orinoco_usb patches had a boolean variable controlling
whether spin_lock_bh was used, or irq based locking. This version
provides wrappers for the lock functions and the drivers specify the
functions pointers needed.

This will introduce a performance penalty, but I'm not expecting it to
be noticable.
