mmc: litex_mmc: Use DIV_ROUND_UP for more accurate clock calculation
The previous clock uses roundup_pow_of_two() to calculate the core
clock frequency. It does not meet the actual hardware meaning.
The actual frequency is calculated by "ref_clk / ((div >> 1) << 1)".
Fix the clock divider calculation.
