ASoC: codecs: zl38060: Mark OF related data as maybe unused

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

sound/soc/codecs/zl38060.c:611:34: error: ‘zl38_dt_ids’ defined but not used [-Werror=unused-const-variable=]

ASoC: zl38060: Remove now redundant non_legacy_dai_naming flag

The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

ASoC: zl38060: Setup parent device and get rid of unnecessary of_node assignment

Some of the drivers do not set parent device. This may lead to obstacles
during debugging or understanding the device relations from the Linux
point of view. Assign parent device for GPIO chips created by these
drivers.

While at it, let GPIO library to assign of_node from the parent device.

ASoC: Add initial ZL38060 driver

The ZL38060 is a "Connected Home Audio Processor" from Microsemi,
which consists of a Digital Signal Processor (DSP), several Digital
Audio Interfaces (DAIs), analog outputs, and a block of 14 GPIOs.

This driver supports only a tiny subset of the chip's functionality
and possible configurations:
- bypass mode (whole dsp block is bypassed)
- chip's I2S DAI routed directly to/from DACs and microphone
- chip's internal clock is driven by a 12 MHz external crystal
- chip's DAI connected to CPU is I2S, and bit + frame clock master
- chip must be strapped for "host boot": in this mode, firmware will
be provided by this driver.
