Subject: [PATCH v7 09/11] net: pch_gbe: Convert to mdiobus and phylib

From: Andrew Lunn <andrew@...n.ch>

Convert this driver to use the mdio bus and phylib infrastructure. It
will then use the common AT803X PHY driver, rather than use its own
code. Have the shared code also handle the GPIO used to reset the PHY.

Over all, these changes should make it easier to use other PHYs with the
MAC chip, and reduces the lines of code.

[paul.burton@...s.com:
  - Select CONFIG_PHYLIB.
  - Drop selection of CONFIG_MII.
  - Imply AT803X_PHY for X86_32, rather than selecting it for all.
  - Add GPIOF_ACTIVE_LOW to the minnow PHY reset GPIO flags.
  - Rebase atop changes in the rest of the series.
  - Drop the AR8031 PHY hibernation disable fixup.]
