usb: host: xhci-plat: Set XHCI_STATE_REMOVING before resuming XHCI HC
There are situations during the xhci_resume() sequence, which allows for re-initializing of the XHCI HC. However, in case the HCD is being removed, these operations may not be needed. Set the removal state before issuing the runtime PM get on the XHCI device, so that the XHCI resume routine will know when to bypass the re-init logic.
