This reverts commit d376ca6716.
It's reported that when using Radxa CM5 with RPI CM4 IO board,
USB2.0 host ports don't work.
By default RK3588 USB DRD DWC3_0 (usb@fc000000) is set in otg mode.
In hardware, RK3588 TYPEC0_USB20_OTG_ID is pulled down to groud
by a 2.2k resistor.
It is needed to perform GCTL_CORE_SOFTRESET during bootup.

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 Restructured Text 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.
