The usb_updater code comparing versions to decide which one is newer
filters out values in excess of 1000 to not consider dev build
versions to be newer than the released versions.
In fact this logic is flawed: with node locked RO it is possible to
build dev (self signed) version, which can run on the device, and this
version should take over the released version, if it is currently
present on the device.
If the RO is not node locked, the dev RW version will not verify, so
it is safe to download it to the chip, it would be ignored.
BRANCH=cr50
BUG=none
TEST=with this patch applied it is possible to update self signed
versions running on H1 (the updater considers them newer than
0.0.18 and sends the chip the vendor command to enable the
downloaded image after download completes).
