Merge branch 'marvel10g-suspend-resume'

Antoine Tenart says:

====================
net: phy: marvell10g: implement suspend/resume callbacks

This series implements the suspend/resume callbacks in the marvell10g
PHY driver.

Thanks,
Antoine

Since v3:
  - Use the new phy_set/clear_bits_mmd() instead of phy_modify_mmd().
  - Use VEND2.f001.11 to power down the port instead of the per-mode
    LPOWER.

Since v2:
  - Removed the third patch, setting the PHY in low power by default, as
    the change was controversial.
  - Rebased on the latest net-next.

Since v1:
  - Fixed a mix up in the patches where two implementations of the
    suspend/resume callbacks were kept in the driver.
  - Rebased on the latest net-next.
