USB connector corresponding to USB port 0 driven either by EHCI/OHCI or Renesas
USBHS gadget controller. And we'd like the host/gadget drivers to work based on
the cable type connected. An 'extcon' driver for MAX3355 has been written, so we
only need to bind to it via device tree which I'm doing in this patch.
(Perhaps, it would also make sense to use OTG HNP when the USBHS host mode is
active and a B-cable is connected but I don't have access to host-capable USBHS,

drivers: usb: dwc2: remove 'force' parameter from kill_all_requests()
This patch fixes in simpler way the bug described in [1] and [2]. It
looks like DWC2 is the only UDC driver that doesn't force usb requests
to complete in ep_disable() function. This causes described problem,
because we have no guarantee that all requests will be completed before
unbind of usb function.
To fix this problem we force all requests of disabled endpoint to complete.
Also currently running request is not handled. This allowed to simplify
code of kill_all_requests() function, because 'force' parameter is always
set to true, so we don't need it anymore.
In s3c_hsotg_rx_data() we change function used to print message when active
request is NULL from dev_warn() to dev_dbg(), because such situation is
harmless for driver and now it can take place during normal endpoint
disabling.
