The hardware bug in POWER9 preventing use of the DAWR was fixed in DD2.3. Set the CPU_FTR_DAWR feature bit on these newer systems to start using it again, and update the documentation accordingly. The CPU features for DD2.3 are currently determined by "DD2.2 or later" logic. In adding DD2.3 as a discrete case for the first time here, I'm carrying the quirks of DD2.2 forward to keep all behavior outside of this DAWR change the same. This leaves the assessment and potential removal of those quirks on DD2.3 for later.
