Update XMEGA board drivers to use the port inversion feature of the XMEGA architecture rather than performing the inversion in software. Add partially completed XMEGA-B1-XPLAINED Dataflash board driver and revert implementation of the XMEGA-A3BU-XPLAINED Dataflash driver as the chip is connected to the USART, not the SPI interface.
