During quick plug/removal of OTG adapter during dual-role testing
it can happen that xhci_alloc_device() is called for the newly
detected device after the DRD library has called xhci_stop to
remove the HCD.
If that is the case, just fail early to prevent the following warning.
[ 154.732649] hub
For whatever reason if XHCI died in the previous instant
then it will never recover on the next xhci_start unless we
clear the DYING flag.

xhci_stop will be called twice, once for the shared hcd
and again for the primary hcd.
We stop the XHCI controller in any case so clean up
everything on the first call else we can timeout
waiting for pending requests to complete.

We initiate dwc2 usb controller in BIOS, dwc2_core_reset() should
be called before dwc2_get_hwparams() to reset core registers to
default value. Without this the FIFO setting might be incorrect
because calculating FIFO size need power-on value of
GRXFSIZ/GNPTXFSIZ/HPTXFSIZ registers.

Hi,
Plugging and unplugging a USB-OTG adapter with a USB device into a
am437x-gp-evm dual-role port (USB1) causes XHCI to malfunction
and USB device to be no longer detected after a few iterations.
The triggering case is so
1) USB1 in peripheal mode
2) plug OTG adapter with USB device
3) USB1
When using the OTG/drd library we can call hcd_add/remove
consecutively without and hcd_alloc so flags can be stale.
If the HC dies due to whatever reason then without this
patch we get the below error on next hcd_add.
[ 91.494257] xhci-hcd xhci-hcd.0.auto: HC died; cleaning up
[ 91.502068]
Else it races with xhci_setup_device
