ASoC: rt-sdw*: add __func__ to all error logs

The drivers for Realtek SoundWire codecs use similar logs, which is
problematic to analyze problems reported by CI tools, e.g. "Failed to
get private value: 752001 => 0000 ret=-5". It's not uncommon to have
several Realtek devices on the same platform, having the same log
thrown makes support difficult.

This patch adds __func__ to all error logs which didn't already
include it.

No functionality change, only error logs are modified.

ASoC: codecs: constify static sdw_slave_ops struct

The struct sdw_slave_ops is not modified and sdw_driver takes pointer to
const, so make it a const for code safety.

ASoC: rt712-sdca-dmic: enable pm_runtime in probe, keep status as 'suspended'

This patch suggests enabling pm_runtime during the probe, but marking the
device as 'active' only after it is enumerated. That will force a
dependency between the card and the codec, pm_runtime_get_sync() will
have to wait for the codec device to resume and hence implicitly wait
for the enumeration/initialization to be completed. In the nominal
case where the codec device is already active the get_sync() would
only perform a ref-count increase.

The changes are directly inspired by RT711 and RT711-sdca changes.

ASoC: SoundWire codecs: make regmap cache-only in probe

The SoundWire bus may start after the probe where the SoundWire ASoC
components are registered. This creates a time window where the card
can be created and the registers be accessed.

As discussed on the mailing list, we can't really control when codecs
are enumerated and initialized, but we can make sure the access to the
codecs is cached until the hardware is accessible.

This patch configures regcache_cache_only() with a 'true' parameter in
the probe function, and a 'false' parameter in the io_init routine.

The rt5682 is handled through a different patch due to its specific
cache handling.

ASoC: rt712: Use maple tree register cache

The rt712 can only support single register read and write operations so
does not benefit from block writes. This means it gets no benefit from
using the rbtree register cache over the maple tree register cache so
convert it to use maple trees instead, it is more modern.
