[PATCH 6/8] spi: spi-ep93xx: don't bother calculating the divisors in ep93xx_spi_setup()

[H Hartley Sweeten <hartleys@visionengravers.com>]

The divisors needed to generate the SPI clock are calculated per
transfer based on the t->speed_hz. There is no reason to calculate
them in ep93xx_spi_setup().
