gpu: host1x: convert MIPI to use operation function pointers
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.
