ec_sync: Use vboot2 context instead of cparams
Copy sync-related flags from cparams / vboot1 shared data to the
equivalent vboot2 structs. This removes the need for ec_sync to
access the old structs, which are on their way out.
No change in functionality.
BUG=chromium:611535

TEST=make -j runtests; build bob firmware and boot it
