kw_spi: fix clock prescaler computation
The computation was not correct with low clock values: setting a 1MHz clock would result in an overlap that would then configure a 25Mhz clock. This patch implements a correct computation method according to the kirkwood functionnal spec. table 600 (Serial Memory Interface Configuration Register).
