tqma6: fix sf detection
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(..). Signed-off-by: Markus Niebel <Markus.Niebel@tq-group.com>
