ASoC/soundwire: log actual PING status on resume issues
Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:
we've been stuck with problems in the dual-amplifier configurations where
one of the two devices seems to become UNATTACHED and never regains sync,
see https://github.com/thesofproject/linux/issues/3638.
This is a rather infrequent issue that may happen once or twice per month,
but still it remains a concern.
One possibility is that the device does lose sync but somehow our hardware
detection fails to see it resync.
This series just adds a basic read directly from the PING frames to help
confirm if yes/no the device regain sync.
