[PATCH 04/10] memory: tegra: Make per-SoC setup more generic

[Thierry Reding <thierry.reding@xxxxxxxxx>]

From: Thierry Reding <treding@xxxxxxxxxx>

The current per-SoC setup code runs at a fairly arbitrary point during
probe, thereby making it less flexible for other SoC generations. Move
the call around slightly, which will allow it to be used for other
implementations.
