When I added command queue engine (CQE) support for the Rockchip eMMC
controller, I missed that RK3576 has a separate platform data struct.
While things are working fine on RK3588 (I tested the ROCK 5B) and
the suspend issue is fixed on the RK3576 (I tested the Sige5), this
results in stability issues. By also adding the necessary hooks for
the RK3576 platform the following problems can be avoided:

Note that the above problems do not necessarily happen with every boot.

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.
