ALSA: hda: cs35l56: Enable low-power hibernation mode on i2c

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.
