ASoC: cs35l45: Hibernation support
...
Adds support for a low-power Hibernation State.
Add support for a low-power hibernation state for the DSP. In
this state the DSP RAM contents are maintained, such that
firmware does not need to be re-downloaded, but the rest of the
chip's register state is lost.
Entry to this state is achieved via the register interface
(either by an external driver using the control port, or the
programmable DSP). Exit from this state is triggered by activity
on device GPIO pins, intended SPI transaction, or I2C
transaction with intended slave address.

ASoC: cs35l45: Remove separate tables module
...
There is no reason to have a separate module for the tables file it just
holds regmap callbacks and register patches used by the main part of the
driver. Remove the separate module and merge it into the main driver
module.
