Richard Zhu c221cbf8dc PCI: imx6: Enable the Vaux supply if available
When the 3.3Vaux supply is present, fetch it at the probe time and keep it
enabled for the entire PCIe controller lifecycle so that the link can enter
L2 state and the devices can signal wakeup using either Beacon or WAKE#
mechanisms.

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.
