Deadzones for gyro - for broken controllers

[C0rn3j]

DS4 gyro over hidraw evdev moves to the right constantly under mouse action.

Does not happen under DualSense.

My DS4 is a chinese knockoff, maybe it's just bugged in the firmware?

EDIT: Bugged firmware. Wonder if a deadzone should be implemented for this...
