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.
