[Why] The inbox1 infrastructure is deprecated, so to support display power features requiring a DMUB interlock moving forward extend the inbox0 locking conditions to also include Replay or PSR. [How] Implemented a series of changes to improve HW lock handling: - Deprecated should_use_dmub_inbox1_lock() and guarded it with DCN401 flag. - Migrated lock checks into inbox0 helpers and added PSR/Replay enablement checks to ensure correct behavior. - Updated HWSS fast update path to acquire HW lock as needed using the new helpers.

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.
