usb: dwc3: dwc3_power_off_all_roothub_ports: Use ioremap_np when required

Browse source

commit 5ed9cc7143 upstream.

On Apple Silicon machines we can't use ioremap() / Device-nGnRE to map most
regions but must use ioremap_np() / Device-nGnRnE whenever
IORESOURCE_MEM_NONPOSTED is set. Make sure this is also done inside
dwc3_power_off_all_roothub_ports to prevent SErrors.
