Clean up dataflash partitioning
This patch removes the board dependent parts from "drivers/mtd/dataflash.c". Each board relying on this, will have the appropriate code in a new file, "partition.c" in the board directory. board Makefiles updated to use the file. The dataflash partitions are aligned on sector/page boundaries. The CONFIG_NEW_DF_PARTITION was used to create named partitions This is now the default operation, and the CONFIG variable is removed. Signed-off-by: Ulf Samuelsson <ulf@atmel.com>
