usb: dwc3-msm: Simplify OTG_STATE_UNDEFINED handling

In commit 48924e2fe107 ("dwc3: Reset USB controller/PHY after psy
connect indication at bootup") the controller initialization path
was removed from dwc3_msm_probe() and is deferred to when actually
needed, which is when beginning peripheral or host mode. This was
to optimize for the HVDCP charger already-connected case in which
case we want to avoid performing controller initialization which
can disrupt D+/D- linestate.

As part of that change, the OTG_STATE_UNDEFINED state was made
to be the entry point for starting controller initialization.
However, apart from that, the handling is identical to B_IDLE_STATE,
and therefore could be consolidated. And now that charger driver
only notifies us when SDP or CDP types, but not when DCP/HVDCP are
connected, the code can be simplified by removing the duplicate code
between dwc3_initialize() and dwc3_msm_resume().
