Daniel Machon e4d505fda6 net: sparx5: fix default value of monitor ports
When doing port mirroring, the physical port to send the frame to, is
written to the FRMC_PORT_VAL field of the QFWD_FRAME_COPY_CFG register.
This field is 7 bits wide on sparx5 and 6 bits wide on lan969x, and has
a default value of 65 and 30, respectively (the number of front ports).

On mirror deletion, we set the default value of the monitor port to
65 for this field, in case no more ports exists for the mirror. Needless
to say, this will not fit the 6 bits on lan969x.

Fix this by correctly using the n_ports constant instead.

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.
