This can now be re-enabled as the sequence to reliably wake the device has been implemented in the shared ASoC code.
This has a functional dependency on commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice")
To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.
