An usb device can initate a remote wakeup and bring the link out of suspend as dictated by the DEVICE_REMOTE_WAKEUP feature selector. Add support to handle this packet and set the remote wakeup capability. Some hosts may take longer time to initiate the resume signaling after device triggers a remote wakeup. So add async support to the wakeup API by enabling link status change events.

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.
