Drivers.h: Rename device_{read|write}_pages back to device_{read|write}v_hook. 

They are not about reading and writing pages, but just iovecs.
As the passed iovecs use void*s, it can't possibly be working with
physical pages on 32-bit systems with PAE.

It appears nothing uses or implements these functions anyway,
as there was nothing else in the tree I had to adjust after making
this change...
