Kai-Heng Feng d742e98740 USB: Disable LPM on WD19's Realtek Hub 
commit b63e48fb50e1ca71db301ca9082befa6f16c55c4 upstream.

Realtek Hub (0bda:0x0487) used in Dell Dock WD19 sometimes drops off the
bus when bringing underlying ports from U3 to U0.

Disabling LPM on the hub during setting link state is not enough, so
let's disable LPM completely for this hub.

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.
