hwmon/aspeed-pwm-tacho: Increase tachometer read timedev-5.0-raptor-04-16-2019
On the Blackbird desk-side systems we expect users will be running large fans very slowly. The current tachometer reading drops to zero under those conditions, resulting in failed fan detection systems kicking in. Increase the tachometer read time to allow for slower fans to return a valid speed. This does make read slower, but more advance fan control software should be able to compensate via e.g. PID loops.
