[PATCH v2] ASoC: dt-bindings: simple-card: Document simple-audio-card, plat

[Faiz Abbas]

The simple card driver already has support for a simple-audio-card,plat
property but its not reflected in the documentation. Add documentation
for this plat property.

Changes since v1:
1. Updated commit message to indicate the property already exists
2. Removed redundant example
3. Fixed formatting issue found by 'make DT_CHECKER_FLAGS=-m dt_binding_check'
