Convert existing MIPI code to use operation function pointers, a necessary step for supporting Tegra20/Tegra30 SoCs. All common MIPI configuration that is SoC-independent remains in mipi.c, while all SoC-specific code is moved to tegra114-mipi.c (The naming matches the first SoC generation with a dedicated calibration block). Shared structures and function calls are placed into tegra-mipi-cal.h.
