tcpmv2: Fix SOP' DiscoverIdent retries.
The PE DRP state machine was sending retries of SOP' DiscoverIdent
without any delay. This sets the delay between SOP' DiscoverIdent to
tDiscoverIdentity (45 ms). The EC uses this delay regardless of the
explicitly contract state.
BUG=b:166650426
BRANCH=none
TEST=make buildall
TEST=Connect SNK device without emarker cable. Observe retries are
spaced by at least 45ms.
TEST=Connect emarker cable and verify cable identity is discovered.
