Sven Peter 8404a1b1f5 usb: dwc3: dwc3_power_off_all_roothub_ports: Use ioremap_np when required 
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
