ALSA: hda: cs35l56: Enable low-power hibernation mode on SPI
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.
