phy: Revert toggling reset changes.

commit 7b566f70e1 upstream.

This reverts:

ef1b5bf506 ("net: phy: Fix not to call phy_resume() if PHY is not attached")
8c85f4b812 ("net: phy: micrel: add toggling phy reset if PHY is not  attached")

Andrew Lunn informs me that there are alternative efforts
underway to fix this more properly.
