commit 235fef6c7fd341026eee90cc546e6e8ff8b2c315 upstream. [Why] MALL size available can vary for different SKUs. Use num_chans read from VBIOS to determine the available MALL size we can use [How] Define max_chans for DCN32 and DCN321. If num_chans is max_chans, then return max_chans as we can access the entire MALL space. Otherwise, define avail_chans as the number of available channels we are allowed instead. Return corresponding number of channels back and use this to calculate available MALL size.

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.
