Subject: [PATCH 0/4] Improve some Adreno Device Tree nodes

There are a couple of issues with some of the existing Adreno DT nodes:
- opp-level is used wrongly instead of required-opps
- the correct power domain for scaling is not always selected
- some frequencies are missing

And up until now, the power domain was not even scaled at all, until
the introduction of commit "Enable optional icc voting from OPP tables".

This series tries to address all of these. 8916 and 8996 didn't explode,
8998 could use some testing.
