usb: typec: tcpm: Fix undefined behavior due to shift overflowing the…

… constant

Fix:

  drivers/usb/typec/tcpm/tcpm.c: In function ‘run_state_machine’:
  drivers/usb/typec/tcpm/tcpm.c:4724:3: error: case label does not reduce to an integer constant
     case BDO_MODE_TESTDATA:
     ^~~~

See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
details as to why it triggers with older gccs only.
