The VP_REG_GET function takes the start and end bits as parameter and
will generate a mask out of them.

This makes it difficult to share the masks between callers, since we now
need two arguments and to keep them consistent.

Let's change VP_REG_GET to take the mask as an argument instead, and let
the caller create the mask. Eventually, this mask will be moved to a
define.
