HID: steelseries: Correct Arctis 9 battery calibration range

Browse source

Map the Arctis 9 raw battery value over 0x64 (empty) to 0x9a (full)
instead of 0x68 to 0x9d. These values match the HeadsetControl project
[1] and fit the calibration points from an independent reverse
engineering of the battery tray (about 25% at raw 112, 50% at raw 125)
[2].

I do not have this headset. The values come from those references and
were not measured directly.
