[PATCH 5/8] ASoC: aw88399: add channel setter for HDA side codec

Add aw88399_dev_set_channel() to the shared library so that the HDA side
codec driver can set the amplifier's channel assignment without
including the aw88395 device header directly.

The AW88399's struct aw_device is defined in aw88395_device.h, which
lives under sound/soc/codecs/aw88395/. Without this accessor, the
HDA driver would need a cross-subsystem relative include path to
access the channel field. Providing a setter in the library keeps the
interface clean and avoids coupling the HDA driver to ASoC-internal
headers.
