Convert stmmac to use phylink managed EEE support rather than delving
into phylib:
1. Move the stmmac_eee_init() calls out of mac_link_down() and
mac_link_up() methods into the new mac_{enable,disable}_lpi()
methods. We leave the calls to stmmac_set_eee_pls() in place as
these change bits which tell the EEE hardware when the link came
up or down, and is used for a separate hardware timer. However,
symmetrically conditionalise this with priv->dma_cap.eee.
2. Update the current LPI timer each time LPI is enabled - which we
need for software-timed LPI.
3. With phylink managed EEE, phylink manages the receive clock stop
configuration via phylink_config.eee_rx_clk_stop_enable. Set this
appropriately which makes the call to phy_eee_rx_clock_stop()
redundant.
4. From what I can work out, all supported interfaces support LPI
signalling on stmmac (there's no restriction implemented.) It
also appears to support LPI at all full duplex speeds at or over
100M. Set these capabilities.
5. The default timer appears to be derived from a module parameter.
Set this the same, although we keep code that reconfigures the
timer in stmmac_init_phy().
6. Remove the direct call to phy_support_eee(), which phylink will do
on the drivers behalf if phylink_config.eee_enabled_default is set.

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.
