rammus: fix incorrect power mode configuration for the USB Type-A

On Rammus, the power mode of the USB Type-A is CDP. However, the default
configuration is SDP2. We don't meet any problem on previous setting
because of missing CONFIG_USB_PORT_POWER_SMART_INVERTED.
This patch fixes the incorrect CONFIG in board.h.

BUG=none

     connect phone to type-a port, CDP works
