ASoC: dt-bindings: awinic,aw88395: Add properties for multiple PA support 



Add two properties, the "awinic,audio-channel" property and the
"awinic,sync-flag". The "awinic,audio-channel" is used to make
different PA load different configurations, the "awinic,sync-flag"
is used to synchronize the phases of multiple PA. These two properties
will be read by the corresponding driver, allowing multi-PA to
achieve better playback effect.
