usb: dwc_otg_310: set operational mode of phy to normal when suspend for rk3368

The phy driver of otg port set operational mode to non-driving
when suspend and set to normal when resume. But if we connect
with low speed, it may be disconnected after suspend and resume
by the changing of operational mode. In addition, the linestate
change interrupt flag can't be cleared if the operational mode
is non-driving. This patch set operational mode to normal even
if the phy is suspended, and make sure that operational mode is
same during suspend and resume.
