[Why] We want to log DMCUB trace buffer events as Linux kernel traces. [How] Register an IRQ handler for DMCUB outbox0 interrupt in amdgpu_dm, and log the messages in the DMCUB tracebuffer to a new DMCUB TRACE_EVENT as soon as we receive the outbox0 IRQ from DMCUB FW.

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.
