USB: typec: fix const issue in typec_match()

[ Upstream commit ae4432e01dd967a64f6670a152d91d5328032726 ]

typec_match() takes a const pointer, and then decides to cast it away
into a non-const one, which is not a good thing to do overall.  Fix this
up by properly setting the pointers to be const to preserve that
attribute.
