memory: tegra: fix unused-function warning

The tegra186_mc_client_sid_override() is only called from
an #ifdef block:

drivers/memory/tegra/tegra186.c:74:13: error: 'tegra186_mc_client_sid_override' defined but not used [-Werror=unused-function]
   74 | static void tegra186_mc_client_sid_override(struct tegra_mc *mc,
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Add another #ifdef around the called function.
