A search of the latest datasheets for the AT90PWM[1,2,3] show that ADTS3 and ADHSM bits are included in the ADCSRB register.

Agree about ADTS3.

ADHSM was supposed to be discontinued some years ago, and
we thus removed it from all avr-libc header files.  Seems
like a cut&paste-o to me that it still reappears in some
datasheets.  I opened an ATticket to see whether it is
really supposed to be there.  (Basically, all AVR ADCs
used to have that bit, but it was eventually found to be
just increasing power consumption without any actual effect
on the ADC speed.  That's why it has once been removed.)

The attached patch addes these Bits to the register ADCSRB

ADHSM   7   /* ADC High Speed Mode */
ADTS3   3   /* ADC Auto Trigger Source 3 */
