[PATCH v2 2/4] dt-bindings: memory-controllers: tegra210: Allow fallback compatible

[Aaron Kling via B4 Relay]

From: Aaron Kling <webgeek1234@xxxxxxxxx>

The nvidia,tegra21-emc compatible is required by the Nvidia Android
bootloader to copy emc training value into the kernel dt. So allow this
as a fallback compatible to avoid needing to change the driver.
