Document the DPU for Qualcomm SA8775P platform. Signed-off-by: Mahadevan <quic_mahap@xxxxxxxxxxx> --- [v2] - Use fake DISPCC nodes to avoid clock dependencies in dt-bindings. [Dmitry] - Update bindings by fixing dt_binding_check tool errors (update includes in example), adding proper spacing and indentation in binding example. [Dmitry, Rob] - Capitalize clock names in description.
