[U-Boot] [PATCH] revert "tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode"

[Zhao Chenhui]

On P2020DS and MPC8572DS, the link to SGMII card which use Vitesse
VSC8234 PHY can't come up. Current TBI PHY settings(TBICR_SETTINGS)
for SGMII mode cause link problems.

Revert commit 46e91674fb4b6d06c6a4984c0b5ac7d9a16923f4, and fix it.
