commit 764d31cacfe48440745c4bbb55a62ac9471c9f19 upstream.
Following a similar reinstate for the KSZ9031.
Older kernels would use the genphy_soft_reset if the PHY did not implement a .soft_reset.
Bluntly removing that default may expose a lot of situations where various PHYs/board implementations won't recover on various changes. Like with this implementation during a 4.9.x to 5.4.x LTS transition. I think it's a good thing to remove unwanted soft resets but wonder if it did open a can of worms?
Atleast this fixes one iMX6 FEC/RMII/8081 combo.
