ARM: tegra: Enable SMMU when going non-secure
Make sure to enable the SMMU when booting the kernel in non-secure mode.
This is necessary because some of the SMMU registers are restricted to
TrustZone-secured requestors, hence the kernel wouldn't be able to turn
the SMMU on. At the same time, enable translation for all memory clients
for the same reasons. The kernel will still be able to control SMMU IOVA
translation using the per-SWGROUP enable bits.
