[PATCH 4.19 01/89] phy: Revert toggling reset changes.

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: David S. Miller <davem@davemloft.net>

commit 7b566f70e1bf65b189b66eb3de6f431c30f7dff2 upstream.

This reverts:

ef1b5bf506b1 ("net: phy: Fix not to call phy_resume() if PHY is not attached")
8c85f4b81296 ("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.
