Alexey Charkov 05b80cd1f3 arm64: dts: rockchip: Remove non-functioning CPU OPPs from RK3576
Drop the top-frequency OPPs from both the LITTLE and big CPU clusters on
RK3576, as neither the opensource TF-A [1] nor the recent (after v1.08)
binary BL31 images provided by Rockchip expose those.

This fixes the problem [2] when the cpufreq governor tries to jump
directly to the highest-frequency OPP, which results in a failed SCMI call
leaving the system stuck at the previous OPP before the attempted change.

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.
