SPI hibernation is now supported with the latest hibernation/wake sequences in the shared ASoC code.
This has a functional dependency on two commits:
commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice")
commit a47cf4dac7dc ("ASoC: cs35l56: Change hibernate sequence to use allow auto hibernate")
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.
