Revert "tegra: Introduce SRAM repair on tegra124"
This reverts commit 701b7b1d2cf657d435d2bd6caf43d0247d37220d. It will be immediately replaced by a different implementation that is more complete and runs are more targetted times. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
