ASoC: SOF: amd: Use dedicated MBOX for ACP and PSP communication
We are currently using generic PSP Mailbox register for sending SHA
complete command to PSP but observe random arbitration issue during
PSP validation as MP0_C2PMSG_26_REG used by other kernel modules.

Use separate mailbox registers and doorbell mechanism to send SHA_DMA
complete command to PSP. This fixes such validation issues and added
flexibility for sending more ACP commands to PSP in future as new mbox
registers i.e MP0_C2PMSG_114_REG and MP0_C2PMSG_73_REG are dedicated
by PSP for ACP communications.

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.
