[PATCH V2] ARM: tegra: Re-add removed SoC id macro to tegra_resume()

From: Dmitry Osipenko
Date: Wed Oct 08 2014 - 15:34:11 EST

Commit d127e9c5c5bc1ee22a7b1fe804397cddd132f756 ("ARM: tegra: make tegra_resume
can work with current and later chips") removed tegra_get_soc_id macro leaving
used cpu register unassigned and as result causing execution of unintended code
on tegra20. Fix it by re-adding macro.
