Bug description:
[Impact]
We have a couple of lenovo latops models which have cirrus-logic side
codec between realtek codec and speaker, it plays a role as amplifier,
we need to enable this side-codec, otherwise the speaker can't output
sound.
[Fix]
Backport codec patches and some i2c and acpi detection patches from
mainline kernel and linux-next
[Test]
boot the patched kernel, run speaker test, both left and right channel
could work well.
[Where problems could occur]
If it could introduce regression, it will be on soc wm_adsp codec
drivers, since most of patch are adding new codec drivers, it will
not touch existing codec drivers. If a machine with wm_adsp codec
can't output sound or record sound, it means this SRU introduce
the regression on wm_adsp driver, but this possibility is very
low, since all patches are picked from mainline kernel.
