I very strongly don't want to use the syscon concept on Tegra. Instead,
I want only the CAR driver touching the CAR registers. If other drivers
need some CAR registers manipulated, that should happen by that other
driver calling some explicit semantic API in the CAR driver to do so.
Take a look at how the Tegra SMMU and Tegra AHB driver communicate for
an example.
