memory: tegra: Protect SID override call under CONFIG_IOMMU_API

tegra186_mc_client_sid_override() is protected under CONFIG_IOMMU_API.
Call to this function is being made from tegra186_mc_resume() without
any protection which is leading to build failure when CONFIG_IOMMU_API
is not set. Fix this by protecting SID override function call from
tegra186_mc_resume() under CONFIG_IOMMU_API.
