"acm_aud_clk0_sel" and "acm_aud_clk1_sel" are registered by this ACM
driver, but they are the parent clocks for other clocks, in order to
use assigned-clock-parents in device tree, the ".fw_name" can't be used,
need to assign the clk_hw pointer for the imx8qm_mclk_sels[],
imx8qxp_mclk_sels[], imx8dxl_mclk_sels[].

changes in v2:
- don't use string name, but use the clk_hw pointer for "acm_aud_clk0_sel"
  and "acm_aud_clk1_sel"
