USB: dwc3_otg: Reset hardware before starting peripheral

USB endpoints can be configured either in DBM or non-DBM mode.
DBM mode is used for BAM to BAM uses case e.g. QDSS, and
non-DBM mode is used for normal device use.
Once an endpoint is configured DBM mode mode, hardware has
to be RESET and re-initialized if endpoint has to be used in
non-DBM mode e.g. changing USB composition from QDSS to non-QDSS.

Currently hardware is RESET as part of moving from host to
peripheral mode. Move this RESET from stop_host to start_peripheral.
Additionally, user is required to reconnect USB cable for RESET to
take place.
