[U-Boot] [PATCH] ot1200: fix sf detection

[Christian Gmeiner]

Commit 155fa9af95ac5be857a7327e7a968a296e60d4c8 changed the way
to define a GPIO line, which can be used to force CS high
across multiple transactions. In order to fix sf detection
change board code to make use of board_spi_cs_gpio(..).
