This converts the sniper board (LG P970) to device-tree control and DM I2C, both for SPL and U-Boot.
Note that we lose the call to board_mmc_power_init to enable power for MMC2. This is now expected to take place through proper regulators, which are not yet available with the twl4030 driver. The call to twl4030_power_mmc_init is moved to spl_board_init for now.
