Now that MTL is going to start providing two GTs, there are a few more
places in the driver that need to iterate over each GT instead of
operating directly on gt0.  Also some more deliberate cleanup is needed,
in cases where we fail GT/engine initialization after the first GT has
been fully setup.

v2:
 - Drop unnecessary helper function.  (Janusz)
 - Consolidate some adjacent GT loops (Daniele)
