Currently, the .port_set_rgmii_delay hook is missing for the 88E6320 family, which causes failure to retrieve an IP address via DHCP. Add mv88e6320_port_set_rgmii_delay() that allows applying the RGMII delay for ports 2, 5, and 6, which are the only ports that can be used in RGMII mode. Tested on a custom i.MX8MN board connected to an 88E6320 switch. This change also applies safely to the 88E6321 variant. The only difference between 88E6320 versus 88E6321 is the temperature grade and pinout. They share exactly the same MDIO register map for ports 2, 5, and 6, which are the only ports that can be used in RGMII mode.

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.
