Rongguang Wei a75a6f3fb2 net: stmmac: add to set device wake up flag when stmmac init phy 
[ Upstream commit a9334b702a ]

When MAC is not support PMT, driver will check PHY's WoL capability
and set device wakeup capability in stmmac_init_phy(). We can enable
the WoL through ethtool, the driver would enable the device wake up
flag. Now the device_may_wakeup() return true.

But if there is a way which enable the PHY's WoL capability derectly,
like in BIOS. The driver would not know the enable thing and would not
set the device wake up flag. The phy_suspend may failed like this:

[   32.409063] PM: dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x50 returns -16
[   32.409065] PM: Device stmmac-1:00 failed to suspend: error -16
[   32.409067] PM: Some devices failed to suspend, or early wake event detected

Add to set the device wakeup enable flag according to the get_wol
function result in PHY can fix the error in this scene.

v2: add a Fixes tag.

README 

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.
