Manikanta Maddireddy eef4a35026 PCI: tegra: Fix PLLE power down issue due to CLKREQ# signal
Disable controllers which failed to bring the link up and configure
CLKREQ# signals of these controllers as GPIO. This is required to avoid
CLKREQ# signal of inactive controllers interfering with PLLE power down
sequence.

PCIE_CLKREQ_GPIO bits are defined only in Tegra186, however programming
these bits in other SoCs doesn't cause any side effects. Program these
bits for all Tegra SoCs to avoid a conditional check.

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.
