mb/google/brya: Remove Rcomp resistors override for Nissa

This patch sets the RComp resistor values to default values needed.

BUG=b:231202733
TEST=Build and boot nivviks and nereid. Verify the Rcomp values are set
to default values from debug FSP log.
[SPEW ]  Updating Rcomp Targets:
[SPEW ]   RcompTarget[RdOdt]: 48
[SPEW ]   RcompTarget[WrDS]: 30
[SPEW ]   RcompTarget[WrDSCmd]: 20
[SPEW ]   RcompTarget[WrDSCtl]: 20
[SPEW ]   RcompTarget[WrDSClk]: 20
