usb: renesas_usbhs: fix usbhsc_resume() for !USBHSF_RUNTIME_PWCTRL 

This patch fixes an issue that some registers may be not initialized
after resume if the USBHSF_RUNTIME_PWCTRL is not set. Otherwise,
if a cable is not connected, the driver will not enable INTENB0.VBSE
after resume. And then, the driver cannot detect the VBUS.

Fixes: ca8a282a53 ("usb: gadget: renesas_usbhs: add suspend/resume support")
