The amdgpu_vm interval tree really wants [a, b) intervals,
not fully closed ones. As such convert it to use the new
interval_tree_gen.h, and also rename the 'last' endpoint
in the node to 'end', which is both a more suitable name
for the half closed interval and also reduces the chances
of missing a conversion when doing insertion or lookup.
