Merge branch 'WoL-fixes-for-DP83822-and-DP83tc811'

Dan Murphy says:

====================
WoL fixes for DP83822 and DP83tc811

The WoL feature for each device was enabled during boot or when the PHY was
brought up which may be undesired.  These patches disable the WoL in the
config_init.  The disabling and enabling of the WoL is now done though the
set_wol call.
