This patch moves the functions operating on the hidden debug registers into it's own file, port_hidden.c. The functions prefix is renamed from mv88e6390_hidden_ to mv88e6xxx_port_hidden_, to be consistent with the rest of this driver. The macros are prefixed with MV88E6XXX_ prefix, and are changed not to use the BIT() macro nor bit shifts, since the rest of the port.h file does not use it. We also add the support for setting the Block Address field when operating hidden registers. Marvell's mdio examples for SERDES settings on Topaz use Block Address 0x7 when reading/writing hidden registers, and although the specification says that block must be set to 0xf, those settings are reachable only with Block Address 0x7.

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.
