[PATCH net v1] Revert "net: phy: dp83867: perform soft reset and retain established link"

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

This reverts commit da9ef50f545f86ffe6ff786174d26500c4db737a.

This fixes a regression in which the link would come up, but no
communication was possible.

The reverted commit was also removing a comment about
DP83867_PHYCR_FORCE_LINK_GOOD, this is not added back in this commits
since it seems that this is unrelated to the original code change.

There has been plenty of time given for somebody to investigate this
regression, and nothing has happened. So i agree, lets revert it.
