David Hendricks fd5d6cc019 daisy: move i2c port initialization back into configure_board ...

This patch moves all I2C port initialization into configure_board
to ensure the alternate function gets set properly.

I2C ports should come up in their high-impedance state (Output,
open-drain, output set) and then get set as alternate function.
However, configure_board() runs before gpio_pre_init(), so the
mode register was getting set set back to general purpose output
instead of alt. function.

TODO: Fix gpio_pre_init() so we do not need to explicitly handle port
configuration in configure_board().

BUG=none
TEST=tested on daisy using keyboard
