Reset (aka power off) happens when the reset gpio is made active.
The reset gpio is GPIO_ACTIVE_LOW

Add missed MODULE_DEVICE_TABLE for the driver can be loaded
automatically at boot.

The driver can be compile tested with !CONFIG_OF making certain data

"AVDD" is for analog power supply, "DVDD" is for digital power
supply, they can improve the power management.
As the regulator is enabled in pm runtime resume, which is
behind the component driver probe, so accessing registers in
component driver probe will fail. Fix this issue by enabling
regcache_cache_only after pm_runtime_enable.

snd_soc_component_update_bits() will only update the mask bits,
so remove the redundant snd_soc_component_read32().

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.

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?

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
