usb: dwc3: core: disable device wakeup for rk356x usb host

Browse Source 
RK356x SDK will power off logic and grf module in suspend.
So we don't need to enable device wakeup for rk356x usb host
to keep usb controller PD on. With this patch, it can call
rk356x combphy init by usb_phy_roothub_init during resume,
and fix the usb3.0 host function failure after resume.
