Deleted the old Sensinode 'read mac from flash' routine.

Browse Source 
Since the introduction of a purpose-written routine, the old
generic one (which was written in asm) was never being used.
There was a configuration directive which allowed us to switch
between the two. All references to this configuration directive
have also been removed.
