Revert "net: phy: dp83867: perform soft reset and retain established link"
[ Upstream commit a129b41fe0a8b4da828c46b10f5244ca07a3fec3 ]
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.
