Nicholas Kazlauskas d740a39c3d drm/amd/display: Fix reset sequence with driver direct DMCUB fw load
[Why]
DMCUB encounters a page fault/double exception with driver direct load
because DMCUB is not held in soft reset after releasing secure reset.

The clean shutdown sequence via GPINT is also not executed in this
sequence which leaves hardware behavior in an indeterminate state.

[How]
Move reset earlier in the sequence.

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.
