sunxi: soft-i2c: Fix gpio handling to work with the driver-model
i2c_init_board() gets called before the driver-model (gpio) code is initialized, so move the setup of the soft-i2c pins out of i2c_init_board() and into board_init(), at which time the driver-model setup has been done. Also add proper error checking and properly request the gpios as that is mandatory with the driver-model.
