The return code of regmap_multi_reg_write() call related to "MDSYNC up"
sequence is shadowed by the subsequent regmap_read_poll_timeout()
invocation, which will hit a timeout in case the write operation above
fails.

Make sure cs35l41_global_enable() returns the correct error code instead
of -ETIMEDOUT.

Additionally, to be able to distinguish between the timeouts of
wait_for_completion_timeout() and regmap_read_poll_timeout(), print an
error message for the former and return immediately.  This also avoids
having to wait unnecessarily for the second time.

Enabling the active/passive shared boosts requires setting SYNC_EN, but
*not* before receiving the PLL Lock signal.

Due to improper error handling, it was not obvious that waiting for the
completion operation times out and, consequently, the shared boost is
never activated.

Further investigations revealed the signal is triggered while
snd_pcm_start() is executed, right after receiving the
SNDRV_PCM_TRIGGER_START command, which happens long after the
SND_SOC_DAPM_PRE_PMU event handler is invoked as part of
snd_pcm_prepare().  That is where cs35l41_global_enable() is called
from.

Increasing the wait duration doesn't help, as it only causes an
unnecessary delay in the invocation of snd_pcm_start().  Moving the wait
and the subsequent regmap operations to the SNDRV_PCM_TRIGGER_START
callback is not a solution either, since they would be executed in an
IRQ-off atomic context.

Solve the issue by setting the SYNC_EN bit in PWR_CTRL3 register right
after receiving the PLL Lock interrupt.

Additionally, drop the unnecessary writes to PWR_CTRL1 register, part of
the original mdsync_up_seq, which would have toggled GLOBAL_EN with
unwanted consequences on PLL locking behavior.

Make use of the recently introduced EXPORT_GPL_DEV_PM_OPS() macro, to
conditionally export the runtime/system PM functions.

Replace the old SET_{RUNTIME,SYSTEM_SLEEP,NOIRQ_SYSTEM_SLEEP}_PM_OPS()
helpers with their modern alternatives and get rid of the now
unnecessary '__maybe_unused' annotations on all PM functions.

Additionally, use the pm_ptr() macro to fix the following errors when
building with CONFIG_PM disabled:

ERROR: modpost: "cs35l41_pm_ops" [sound/soc/codecs/snd-soc-cs35l41-spi.ko] undefined!
ERROR: modpost: "cs35l41_pm_ops" [sound/soc/codecs/snd-soc-cs35l41-i2c.ko] undefined!

Replace the remaining dev_err() calls in probe() with dev_err_probe(),
to improve consistency.
