tegra2_mmc_init() is implemented by the Tegra2 MMC driver. Since most of
the Tegra2-based boards will need to call it, this commit exports it in
the new public asm/arch/mmc.h header file to prevent each board from
providing its own prototype.

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

This moves the magic numbers sprinkled about the MMC driver
to a single location in the header file and gives them
meaningful names.

This adds most of the clock functions required by board and driver code:
-query and adjust peripheral clocks
-query and adjust PLLs
-reset and enable control
These functions are plumbed in as required.
