ASoC: fsl_micfil: register platform component before registering cpu dai
There is no defer probe when adding platform component to
snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime()

snd_soc_register_card()
  -> snd_soc_bind_card()
    -> snd_soc_add_pcm_runtime()
      -> adding cpu dai
      -> adding codec dai
      -> adding platform component.

So if the platform component is not ready at that time, then the
sound card still registered successfully, but platform component
is empty, the sound card can't be used.

As there is defer probe checking for cpu dai component, then register
platform component before cpu dai to avoid such issue.

ASoC: fsl_micfil: Don't use devm_regmap_init_mmio_clk
When there is power domain bind with ipg_clk clock,

The call flow:
devm_regmap_init_mmio_clk
   - clk_prepare()
      - clk_pm_runtime_get()

cause the power domain of clock always be enabled after
regmap_init(). which impact the power consumption.

So use devm_regmap_init_mmio instead of
devm_regmap_init_mmio_clk,but explicitly enable
clock when it is used.

ASoC: fsl: drop unneeded snd_soc_dai_set_drvdata
snd_soc_dai_set_drvdata is not needed when the set data comes from

ASoC: fsl: constify static snd_soc_dai_ops structs
The only usage of these is to assign their address to the 'ops' field in
the snd_soc_dai_driver struct, which is a pointer to const. Make them
const to allow the compiler to put them in read-only memory.
