====================
Adding PHY MDI(X) support

I updated all review comments which were given by Andrew and Florian.

This series add support for PHY MDI(X), and implement it for MSCC phys.

Tested on Beaglebone Black with VSC 8531 PHY.

Change set:
v1:
- Initial patch submit the WoL and MDI-X in single set of patches

v2:
- Split the mdi(x) as signal set of patches.
- Remove the out_unlock as suggested by Andrew.
- Add mdix_ctrl parameter in "phy_device" to handle the user configure
  mdi(x). Proposed implementation accepted by Florian.
- phydev->mdix_ctrl initialize with ETH_TP_MDI_AUTO. Ethernet controller
  never initialize this parameter.
- Fix the mdix changes in marvell and microchip driver.
