[PATCH 3.16 030/294] usb: renesas_usbhs: fix usbhsc_resume() for !USBHSF_RUNTIME_PWCTRL

[Ben Hutchings]

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

From: Yoshihiro Shimoda 

commit 59a0879a0e17b2e43ecdc5e3299da85b8410d7ce upstream.

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: ca8a282a5373 ("usb: gadget: renesas_usbhs: add suspend/resume support")
