spi: sunxi: fix CDR2 calculation
The CDR2 divider calculation always yield a frequency greater than the
requested one. Use DIV_ROUND_UP() to keep the frequency equal or below
the requested one. This way, we can also drop the "if div > 0" check
because we know for a fact that div cannot be zero.
FWIW, this aligns the CDR2 calculation with the linux driver.
