At present, TCPM code assumes that local device supports variable/batt pdos and always selects the pdo with highest possible power within the board limit. This assumption might not hold good for all devices. To overcome this, this patch makes TCPM only accept a source_pdo when there is a matching sink pdo. For Fixed pdos: The voltage should match between the incoming source_cap and the registered snk_pdo For Variable/Batt pdos: The incoming source_cap voltage range should fall within the registered snk_pdo's voltage range. Also, when the cap_mismatch bit is set, the max_power/current should be set to the max_current/power of the sink_pdo. This is according to: "If the Capability Mismatch bit is set to one The Maximum Operating Current/Power field may contain a value larger than the maximum current/power offered in the Source Capabilities message’s PDO as referenced by the Object position field. This enables the Sink to indicate that it requires more current/power than is being offered. If the Sink requires a different voltage this will be indicated by its Sink Capabilities message.
