My fault ... I thought it might be easier on the backport to
all the stable and long term kernels if we kept this small at
this stage.  If upstream wants to cleanup all the users in a
subsequent patch, then we can do that too.

Alternatively there is Thomas' suggestion to encode the
range of steppings in the upper bits of driver_data and
avoid touching this structure altogether.
