cosmetic: doc: driver-model: Do not number driver lists

Everytime a dead driver is removed from the list,
we must re-number. This is a painful task.

Try
  git show e53232250 -- doc/driver-model/UDM-serial.txt
  git show 6f62f4207 -- doc/driver-model/UDM-serial.txt
  git show b9f4bc34a -- doc/driver-model/UDM-serial.txt
to see what I mean.

 III) Analysis of in-tree drivers
 --------------------------------
 
-  1) drivers/hwmon/lm81.c
-  -----------------------
+  drivers/hwmon/lm81.c
+  --------------------
   The driver is standard dtt. Simple conversion is possible.
 
 
-  2) drivers/hwmon/ds1722.c
-  -------------------------
+  drivers/hwmon/ds1722.c
+  ----------------------
   The driver is not standard dtt, but interface is similar to dtt.
   The interface has to be changed in order to comply to above mentioned
   specification.
