The patch ("OPP: Add support for parsing the 'opp-level' property")
adds an API enabling a cleaner way to read the opp-level. Let's use
the new API.

Obviously this can't land until we have a tree that contains the patch
adding the API. I believe that means we'll want to target this patch
for 5.2. Luckily it's fine to wait since this patch has no functional
changes--it's all cleanup.
Changes in v2:
- Split into two patches to facilitate landing.
