[ Upstream commit 128d54fbcb14b8717ecf596d3dbded327b9980b3 ]

Following a similar reinstate for the KSZ8081 and KSZ9031.

Older kernels would use the genphy_soft_reset if the PHY did not implement
a .soft_reset.

The KSZ8061 errata described here:
https://ww1.microchip.com/downloads/en/DeviceDoc/KSZ8061-Errata-DS80000688B.pdf
and worked around with 232ba3a51c ("net: phy: Micrel KSZ8061: link failure after cable connect")
is back again without this soft reset.

Fixes: 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
