Now the debugfs files dais/platforms/codecs have a size limit PAGE_SIZE and
the user can not see the whole contents of dai_list/platform_list/codec_list
when they are larger than this limit.

This patch uses seq_file instead to make sure dais/platforms/codecs show the
full contents of dai_list/platform_list/codec_list.

The merge between commit abaca806 ("IIO: ADC: stm32-dfsdm: code
optimization") and commit 2353758b ("IIO: ADC: stm32-dfsdm: avoid
unused-variable warning") left one variable behind that is no longer
needed and can be removed, as shown by the gcc warning:

If bcm2835 is configured as bitclock master calling hw_params()
after prepare() fails with EBUSY. This also makes it impossible to
use bcm2835 in full duplex mode.

The error is caused by the split clock setup: clk_set_rate
is called in hw_params, clk_prepare_enable in prepare. As hw_params
doesn't check if the clock was already enabled clk_set_rate
fails with EBUSY.

Fix this by moving clock startup from prepare to hw_params and
let hw_params properly deal with an already set up or enabled
clock.

The second assignment to res is identical to the previous assignment

In current ALSA SoC, Codec only has .read/.write callback.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

commit 39b5a0f8 ("ASoC: cx20442: don't use reg_cache")
removed .read/.write from driver, but it might breaks non-regmap
driver, because ALSA SoC framework might call it.

To fix this regression, this patch back .read/.write.
and also this patch uses cx20442 internal reg_cache
which is needed for .read/.write.
