The sysclk seems be incorrect since we use the simple card for kylin
board.
The simple card call:
asoc_simple_card_probe ->
asoc_simple_card_dai_link_of ->
asoc_simple_card_sub_parse_of ->
...
clk = of_clk_get(args.np, 0);
if (!IS_ERR(clk))
dai->sysclk = clk_get_rate(clk);
The sysclk come from the first clock, then first clock is hclk_i2s
in i2s for rk3036 dtsi.
So, we can override the clocks to fit the simple card in here.
