Blackfin: blackvme: new board port

The board includes:
 * ADSP-BF561 rev. 0.5
 * 32-bit SDRAM (2 * MT48LC16M16A2TG or MT48LC32M16A2TG)
 * Gigabit Ether AX88180 (ASIX) + 88E1111 rev. B2 (Marvell)
 * SPI  boot flash on PF2 (M25P64 8MB, or M25P128 16 MB)
 * FPGA boot flash on PF3 (M25P64 8MB, or M25P128 16 MB)
 * Spartan6-LX150 (memory-mapped; both PPIs also connected)
 * See http://www.skutek.com/
