ASoC: cs35l56: Disable low-power hibernation mode

Do not allow the CS35L56 to be put into its lowest power
"hibernation" mode. This only affects I2C because "hibernation"
is already disabled on SPI and SoundWire.

Recent firmwares need a different wake-up sequence. Until
that sequence has been specified, the chip "hibernation" mode
must be disabled otherwise it can intermittently fail to wake.

THIS WILL NOT APPLY CLEANLY TO 6.5 AND EARLIER:
We will send a separate backport patch to stable.
