payloads/libpayload/drivers/i8042: Disable scanning on disconnect
This change ensures that keyboard scanning is disabled and keyboard is set to default state while disconnecting the keyboard. This is required to ensure that the controller doesn't keep scanning and buffering keystrokes which could lead to OS drivers reading stale data. BUG=b:110024487 TEST=Verified that kernel driver is able to probe correctly even if multiple keys are pressed during handoff from payload to OS.
