It seems like there's a lot of things in this header that still don't
follow the convention we're trying to standardize on:
 - A bunch of other registers near the top are still mis-sorted.
 - Some registers are using uppercase hex for the register offsets
   rather than the more widely-used lowercase hex.
 - The definition values are indented different amounts.  I think when
   we started cleaning up these register headers we picked column 49
   (via tabs) as the usual starting point for the values.
 - There's a 'struct guc_doorbell_info' and GUC_NUM_DOORBELLS that don't
   seem to be used anywhere in the driver (and probably wouldn't belong
   in a register header anyway).

Rather than just moving this one register, should we do all of those
updates?
