Josua Mayer 794a066688 arm64: dts: marvell: cn9132-clearfog: fix multi-lane pci x2 and x4 ports
The mvebu-comphy driver does not currently know how to pass correct
lane-count to ATF while configuring the serdes lanes.

This causes the system to hard reset during reconfiguration, if a pci
card is present and has established a link during bootloader.

Remove the comphy handles from the respective pci nodes to avoid runtime
reconfiguration, relying solely on bootloader configuration - while
avoiding the hard reset.

When bootloader has configured the lanes correctly, the pci ports are
functional under Linux.

This issue may be addressed in the comphy driver at a future point.

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.
