tegra2: Move board_mmc_init into board files
For Seaboard, this is mostly a cut/paste of board_mmc_init() and pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some missing pinmux_tristate_disable calls for the GPIOs. For Harmony, those functions were modified to configure SDMMC2 (index 2) instead of SDMMC3 (index 1), since that's what is present on the board. However, harmony.c is still missing the required GPIO setup, so neither port is likely to function correctly yet. This will be fixed in the next change. v4: Include board.h to prototype tegra2_mmc_init().
