ASoC: rsnd: setup BRGCKR/BRRA/BRRB on rsnd_adg_clk_control() 



Current adg.c will configure BRGCKR/BRRA/BRRB to output clock
when it start sound. OTAH, rsnd_adg_clk_enable() will enables
clk_a/b/c when driver was probed.
But it is strange, these should be set in the same time.
This patch fixup it.
