Remove funcmux calls from the Tegra20 video driver. Knowledge of pinmux setup must come from either board files or DT; it should not be embedded into board-agnostic driver code. The DT pinmux bindings do not allow drivers to derive funcmux-style information, since the DT bindings are pin-based whereas funcmux is controller-based, so there's no good way to call the existing funcmux APIs from drivers. Converting drivers to use a new (as yet non-existent in U-Boot) API that pulls pinmux information from DT isn't useful for Tegra, since Tegra's DT files don't contain any per-device pinmux tables, so this would simply be extra code that has no effect; doesn't actually set up the pinmux. We are left with moving the pinmux setup functionality into board files. In theory the board files could be converted later to use DT, but that would be a separate change.
