usb: dwc3: core: don't break during suspend/resume while we're dual-role
We can't rely just on dr_mode to decide if we're in host or gadget
mode when we're configured as otg/dual-role. So while dr_mode is
OTG, we find out from the otg state machine if we're in host
or gadget mode and take the necessary actions during suspend/resume.
Also make sure that we disable OTG irq and events during system suspend
so that we don't lockup the system during system suspend/resume.
Known Issue:
when otg-host, usb device disconnects and reconnects after system suspend/resume.
