tegra2: Modify MMC driver to handle power and cd GPIOs
Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and
modify that function to perform all required GPIO initialization. This
removes the need for board files to perform these operations.
Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which
GPIOs to use.
Update affected call-sites in seaboard.c and harmony.c. Note that this
change should make all SD ports work on Harmony, since the required GPIO
setup is now being performed.
v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.
Remove prototype of gpio_config_mmc() from board.h
