spi_mpc83xx: fix clockrate calculation for low speed
Commit a61f5345 (spi_mpc83xx clockrate fixes) broke clockrate calculation
for low speeds. SPMODE_DIV16 should be set if the divider is higher than
64, not only if the divider gets clipped to 1024.
Furthermore, the clipping check was off by a factor 16 as well.
