clk: rockchip: rk3288: i2s_frac adds flag to set parent's rate

The relation of i2s nodes as follows:
          i2s_src               0           0            594000000  0
             i2s_frac           0           0            11289600   0
                i2s_pre         0           0            11289600   0
                   sclk_i2s0    0           0            11289600   0
                   i2s0_clkout  0           0            11289600   0
                      hclk_i2s0 1           1            99000000   0

sclk_i2s0 is the master clock, when to set rate of sclk_i2s0, should
allow to set its parent's rate, by add flag CLK_SET_RATE_PARENT for
"i2s_frac", "i2s_pre", "i2s0_clkout" and "sclk_i2s0".

Tested on rk3288 board using max98090, with command "aplay <music.wav>"
