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.

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.
