[PATCH 3/9] ARM: tegra: Add MIPI calibration DT entries for Tegra114

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Add a device node for the MIPI calibration block on Tegra114. There is
no need to disable it by default because it only enables the clock while
performing calibration and therefore shouldn't be consuming any power
when unused.
