MLK-11870 usb: chipidea: otg: disable term select override for B device

In MLK-11272, we introduce a workaround to resolve data pulse detection
IC issue in i.MX7D, but did not disable the term select override after
the A device becomes B device in some cases: a_idle --> enable term
select override --> b_idle, which cause the B device cannot be enumerated
in b_peripheral mode. This patch is to fix it by disable the term select
and data pulse when A device becomes B device.
