We've added some fields with longer names since we originally wrote
this, so the fields are no longer lined up. Adjust the widths to make
it all look nice again, eg:

  0:mon> dp
  paca for cpu 0x0 @ c000000001fa0000:
   possible                  = yes
   ...
   slb_shadow            [0] = 0xc000000008000000 0x400ea1b217000500
   slb_shadow            [1] = 0xd000000008000001 0x400d43642f000510
   ...
   rfi_flush_fallback_area   = c0000000fff80000   (0xcc8)
   ...
   accounting.starttime_user = 0x51582f07         (0xae8)
