iwlwifi: Adjust blink rate to compensate Clock difference
Adjust led blink rate to compensate on a MAC Clock difference on every
HW. Led blink rate analysis showed an average deviation of 0% on 3945,
5% on 4965 HW and 20% on 5000 series and up.
Need to compensate on the led on/off time per HW according to the
deviation to achieve the desired led frequency
The calculation is: (100-averageDeviation)/100 * blinkTime
For code efficiency the calculation will be:
compensation = (100 - averageDeviation) * 64 / 100
NewBlinkTime = (compensation * BlinkTime) / 64
