Support for DS15/DS25/ES45 (Titan) alpha models (rpb family 38). These systems
are very close to the Tsunami systems (rpb family 34) and share the existing
Tsunami code; the tsc(4) Tsunami controller code is extended to handle the
Titan differences, except for the Titan AGP GART which is left unsupported
for now.
Tested to not cause regressions on DS20 (deraadt@) and ES40 (miod@).
Titan support tested by Sergey Prysiazhnyi on DS25, many thanks for your time!
