Subject: [PATCH 10/13] memory: tegra124-emc: Add the SoC model prefix to
functions
Replace "tegra_emc" with "tegra124_emc" in all functions to:
1. Avoid name clashing with other Tegra EMC drivers which makes it
easier to jump to function definitions,
2. Decode the calltraces a bit easier,
3. Unify with other Tegra MC and EMC drivers, which use the SoC model
prefixes.
No functional impact.
