tsec: Revert to setting TBICR_ANEG_ENABLE by default for SGMII
The following commit:

tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode
Removed setting Auto-Neg by default, however this is believed to be
proper default configuration for initialization of the TBI interface.
Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the
XPedite5370 & XPedite5500 boards that use a Broadcomm PHY which require
Auto-Neg to be disabled to function properly.
This addresses a breakage on the P2020 DS & MPC8572 DS boards when used
with an SGMII riser card. We also remove setting
CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the
default setting is sufficient for them.
Additionally, we clean up the code a bit to remove an unnecessary second
define.
