[UCPD] Add support for non-SOP packets

Allow capturing (and distinguishing) non-SOP packets as well. The
default configuration will just configure SOP packets. For ease of use
the default receive function signature is unchanged as for PD sinks
(which is likely the common usage) just SOP is enough so no need to
differentiate.
