ARM: zynq: Add Z-turn board V5

Adding Z-turn board V5 to resolve the change between:

"Z-TURNBOARD_schematic.pdf" schematics state version 1 to 4 has Atheros AR8035
"Z-Turn_Board_sch_V15_20160303.pdf" schematics state version 5 has Micrel KSZ9031

At this time the S25FL128SAGNFI003 doesn't work because of bug:

*** Warning - spi_flash_probe_bus_cs() failed, using default environment

zynq-zturn was checked on V5 board, same error.

Maybe Z-turn board have the same problem (board with W25Q128BVFIG).
