Jisheng Zhang e835c0a4e2 usb: dwc3: don't reset device side if dwc3 was configured as host-only
Commit c4a5153e87 ("usb: dwc3: core: Power-off core/PHYs on
system_suspend in host mode") replaces check for HOST only dr_mode with
current_dr_role. But during booting, the current_dr_role isn't
initialized, thus the device side reset is always issued even if dwc3
was configured as host-only. What's more, on some platforms with host
only dwc3, aways issuing device side reset by accessing device register
block can cause kernel panic.
