clk: amlogic: gxbb: drop incorrect flag on 32k clock

gxbb_32k_clk_div sets CLK_DIVIDER_ROUND_CLOSEST in the init_data flag which
is incorrect. This is field is not where the divider flags belong.

Thankfully, CLK_DIVIDER_ROUND_CLOSEST maps to bit 4 which is an unused
clock flag, so there is no unintended consequence to this error.

Effectively, the clock has been used without CLK_DIVIDER_ROUND_CLOSEST
so far, so just drop it.
