ASoC: ak5558: Remove redundant snd_soc_component_read32 calls
snd_soc_component_update_bits() will only update the mask bits,
so remove the redundant snd_soc_component_read32().

ASoC: codecs: constify snd_soc_dai_ops structures
The snd_soc_dai_ops structures are only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structures
const as well.

Done with the help of Coccinelle.

ASoC: ak5558: make two structures static
The structure ak5558_pm and soc_codec_dev_ak5558 are local to the
source and do not need to be in global scope, so make them static.
Also make soc_codec_dev_ak5558 static.

Cleans up sparse warnings:
warning: symbol 'ak5558_pm' was not declared. Should it be static?
warning: symbol 'soc_codec_dev_ak5558' was not declared. Should it be
static?

ASoC: ak5558: replace codec to component
Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 0	->	.idle_bias_on = 1
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1
