ASoC: rockchip: pdm: fix regmap_ops hang issue
This is because set_fmt ops maybe called when PD is off,
and in such case, regmap_ops will lead system hang.
enale PD before doing regmap_ops.

Julia Lawall 0966a25887 ASoC: rockchip: constify snd_soc_dai_ops structures
These snd_soc_dai_ops structures are only stored in the ops field of
a snd_soc_dai_driver structure, which is const.  Thus, the
snd_soc_dai_ops structures can be const too.

Done with the help of Coccinelle.

Sugar Zhang fc05a5b222 ASoC: rockchip: add support for pdm controller
The Pulse Density Modulation Interface Controller (PDMC) is
a PDM interface controller and decoder that support PDM format.
It integrates a clock generator driving the PDM microphone
and embeds filters which decimate the incoming bit stream to
obtain most common audio rates.
