Remove hard-coded CRT blanking frobbing for load detection.fbc
CRT blanking needn't be adjusted to perform load detection on 9xx chips, and
the 8xx load detection path now adjusts blanking just during load detection.
Adjusting the blanking interval turned out to cause many monitors to fail to
sync.
