usb: dwc3: imx: avoid calling imx suspend/resume callbacks twice
If a runtime suspend is executed followed by a system suspend, the driver
may invoke dwc3_imx_suspend() twice, which causes enable_irq() to be
called twice as well. This leads to an unbalanced IRQ state and may
trigger warnings or malfunction. Prevent this by checking the pm_suspended
flag before running the imx suspend/resume path.
