dt-bindings: display: tegra: document Tegra132 MIPI calibration device

Document MIPI calibration device found in Tegra132. This compatible
already exists in the Linux kernel, I have just documented it to satisfy
warnings.

Each Tegra SoC generation has unique set of registers which should be
configured. They all differ, hence fallback is not suitable here.
