2015-10-25spi: zynq_qspi: Fix to configure CPOL, CPHA maskJagan Teki
priv->mode is initialized when .set_speed triggers with mode value, so checking mode for configuring CPOL, CPHA using priv->mode is invalid hence use mode from .set_speed argument, and at the end priv->mode will initialized with mode. This patch also replaces formatting string to use speed instead of mode in .set_speed ops. Signed-off-by: Jagan Teki <jteki@openedev.com>
