Add new Master SPI Mode USART serial peripheral driver for the XMEGA and AVR8 architectures.
Modify board Dataflash drivers so that each individual board is responsible for including the correct peripheral driver (SPI or SerialSPI) based on the board connections to the Dataflash chip.
Complete A3BU-XPLAINED and B1-XPLAINED board Dataflash drivers.
