drop: Ignore command version for VBNV CONTEXT command
drop: Ignore command version for VBNV CONTEXT command

The ec driver does not yet pass the command version properly from app
to the EC. This causes a failure when trying to use the vbnvram
context command (23). The thing is that the command version is not
even important for this command, as it was never implemented
differently.

As a quick fix - mark the command descriptor as supporting both
versions. I wonder if we should implement a "don't care" option for
situations like this.
