clk: rockchip: Make calculations use rounding
Let's use DIV_ROUND_CLOSEST for rounding, not just truncating
division. This lets us get closer to the right rate.
Before this:
set_phase(86) delay_nums=26 reg[0xf000420c]=0x468 actual_degrees=83
set_phase(89) delay_nums=27 reg[0xf000420c]=0x46c actual_degrees=86
After this:
set_phase(86) delay_nums=27 reg[0xf000420c]=0x46c actual_degrees=86
set_phase(89) delay_nums=28 reg[0xf000420c]=0x470 actual_degrees=90
