[PATCH 3/3] clk: spacemit: k3: fix missing /2 factor in i2s sysclk dividers

[Troy Mitchell]

The i2s{0,2,3,4,5}_sysclk_div DDNs have an additional fixed 1/2
divider in the hardware IP after the configurable divider, so the
real output rate is:

    rate = parent_rate * num / (den * 2)

Set pre_div to 2 to account for it.
