ASoC: cs35l56: Change hibernate sequence to use allow auto hibernate

If the hardware uses SPI_MOSI, I2C_SCL or I2C_SDA as the wake source
the bus activity of sending HIBERNATE_NOW will wake up the amps that
were already put into hibernate.

ALLOW_AUTO_HIBERNATE tells the firmware to hibernate itself after a
timeout of a few seconds, giving the driver instances time to send this
before any amps have gone into hibernate.
