[RFC PATCH 2/3] memory: tegra: add TLB cache line size

[Tomasz Figa <tfiga@chromium.org>]

From: Vince Hsu <vince.h@nvidia.com>

This patch adds SMMU line size to Tegra SoC data struct to enable SMMU
driver to use this knowledge in code added by further patch.

Also add the missing TLB line number for Tegra124.
