bab - add dead boards and dead chains to stats
bab - add info about number of boards/chips to each Dead Chain
bab - reduce def speed, fix speed staying in ranges and report bank/chips in ioctl() errors
Choose better defaults for min/max/default fan settings for hfa driver.
Correctly measure the hfa max temp and smooth out the changes in its value.
Merge branch 'master' of github.com:ckolivas/cgminer
Only perform a hfa fan speed update if we have new temps to work with.
We should retry only 3 times to get an hfa header response to init since that is more than 1.5 second of waiting.
Use increments of 10 when increasing hfa clock since it may not have 5 MHz granularity internally.
Have some leeway before starting to throttle hfa dies.
Wait for 5 temperature updates in hfa before adjusting fanspeed.
Update authors for removal of gpu/scrypt.
Try one more time to get the hfa header on init since it can take 2 seconds for all 3 boards on a sierra.
Further relax the target temperatures on hfa driver, targetting 88 degrees.
Allow hfa fanspeed to be set via command line.
Clamp initial hfa fanspeed to min/max if passed as parameters.

bab - more speed maangement and dead stats
Ensure we iterate over all dies adjusting temperate for hfa by starting iterating after the last die modified.
Merge branch 'master' of github.com:ckolivas/cgminer
Only adjust clocks if there is no restart in hfa to avoid 2 restarts back to back.
