usb: host: xhci-rcar: Fix timeout in xhci_suspend()
When a USB device is connected to the host controller and
the system enters suspend, the following error happens
in xhci_suspend():
xhci-hcd ee000000.usb: WARN: xHC CMD_RUN timeout
Since the firmware/internal CPU control the USBSTS.STS_HALT
and the process speed is down when the roothub port enters U3,
long delay for the handshake of STS_HALT is neeed in xhci_suspend().
So, this patch adds to set the XHCI_SLOW_SUSPEND.
Fixes: 435cc1138ec9 ("usb: host: xhci-plat: set resume_quirk() for R-Car controllers")
