This reverts commit 794a066688 because it
misunderstood interworking between arm trusted firmware and the common
phy driver, and does not consistently resolve the issue it was intended
to address.
Further diagnostics have revealed the root cause for the reported system
lock-up in a race condition between pci driver probe and clock core
disabling unused clocks.
Revert the wrong change restoring driver control over all pci lanes.
As a temporary workaround for the original issue, users can boot with
"clk_ignore_unused".

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.
