ARM: tegra: Enable non-cached memory
Some boards, most notably those with a PCIe ethernet NIC, require this to avoid cache coherency problems. Since the option adds very little code and overhead enable it across all Tegra generations. Other drivers may also start supporting this functionality at some point, so enabling it now will automatically reap the benefits later on.
