[PATCH v3 1/3] ASoC: Add json-schema documentation for sound-name-prefix

[Sameer Pujar]

The 'sound-name-prefix' is used to prepend suitable strings to a
component widgets or controls. This is helpful when there are
multiple instances of the same component. Add relevant json-schema
and is inspired from sound-name-prefix.txt documentation.
